What is the difference between a real image and a virtual image? Hurry?

The difference between a real image and a virtual image is that the actual light of the real image (converges), the virtual image is made of the actual light (the intersection of the reverse extension line), and the (real) image can be presented on the light screen, while the (virtual) image cannot.

A real image is an image formed by the convergence of actual light rays, so it can be represented on a light screen.

The virtual image is the convergence point of the extension line of the actual light, which is judged by the human eye based on experience, and does not actually exist. The image when you look in the mirror is an illusion. The image formed in the water is a virtual image, the plane mirror is a virtual image, and the real image that can be projected on an object is a slide camera

What can't be is an imaginary image, like an image made of a plane mirror, which is generally a reflection of light.

What is the difference between a real image and an imaginary image?

The light is different.

The essential difference between the real image and the virtual image is that the real image is a muffled chain formed by the convergence of actual light, while the virtual image is formed by the convergence of the reverse extension of the actual light, and no actual light passes through the virtual image. Therefore, the method of distinguishing the real image and the virtual image is also very simple, the best way is to use the light screen to capture, if it can be imaged on the light screen, it is the real image, and vice versa.

Wang stool. Imaging principle: After the light emitted by the object is reflected or refracted by the optical elements, the image formed by the reconvergence is called the real image of the trapped brigade, which is the intersection point of the actual light. In convex lens imaging, the resulting real image is inverted.

If the light emitted by an object is reflected or refracted by an optical element and diverged, the image formed by their intersection after they are extended in reverse is called a virtual image.

Virtual image. It is not actually there, but in the observer.

The image seen in the eye (or just the visual response in the brain), when the observation position is changed, the "image" will change to the "virtual image", for example, "fishing for the moon in the water", seeing the moon in the water is just a reflection, the person on the opposite side may not be able to see a moon shadow in the same position in the water, the reflection of the moon is a "virtual image", magnifying glass.

The images observed in the microscope are also "virtual images".

In the imaging process, the position of the imaging is only related to the imaging conditions, and the "image" obtained has nothing to do with the position of the observer, which is equivalent to the fact that the light is actually emitted from the "image" itself, called the "real image", this image actually exists, no matter what direction the observation is observed, its position will not change belongs to the "real image", such as a projector.

Or the "image" generated by the projector or slide projection on the screen, even if you turn to the back of the screen to observe, a statue in this hall can be observed, and when you observe the front and back of the image, it is like observing a physical object, and the left and right positions will be opposite, and this kind of imaging is called "real or hidden image". That's where the day-to-day difference lies

The real image is the image formed after the convergence of the actual rays of the sail is called the real image, and the virtual image is not the reality, and the virtual image is not the convergence of the intercortex rays of the real state, but the reverse extension of the rays.

The real image is the convergence point of the actual light, which can be received by the fluorescent screen or directly observed by the eyes, and the virtual image is the convergence point of the reverse extension of the actual light, which can only be observed with the eyes, so what is the difference between the real image and the virtual image?

1.The imaging principle of real image and virtual image is different, under normal circumstances, the real image is formed by the convergence of actual sail rays, which can make the negative sensitive to light, and is the intersection point of actual rays; A virtual image is an image formed by the light emitted by an object, which is reflected or refracted by optical elements and diverged, and then intersected by reverse extension.

2.The real image can be displayed in the fluorescent screen, and it can also be directly observed by the eyes, while the virtual image cannot be received through the fluorescent screen and can only be observed with the eyes.

3.The position of the image of the real image and the virtual image is different, when observing with a convex lens, in general, the real image and the virtual image are located on both sides of the convex lens respectively, the real image generally shows that the object and the image are on the same side, and the object of the virtual image and the image are in different directions of the mirror.

Examples of real images: the image on the negative film of the camera of Xiao Kong Nian, the image on the retina of the human eye, the image on the TV screen, the image on the audio of the projector, etc.; Examples of virtual images: objects seen through a magnifying glass, objects in water, mirages, what you see when you look in the mirror, etc.

A virtual image is a physical word that, if the beam of light is divergent, is the intersection of the opposite extension of the actual ray. Its meeting point is called the "virtual image" of the object. The virtual image cannot be reached by the actual optical core code line, so it cannot be undertaken by the optical screen Jian Feng.

The real image, on the other hand, can be taken over by the light screen.

The real image is actually formed by the convergence of light rays, such as a curved lens with a fixed distance buried silver reed imaging, and the virtual image is formed by the convergence of the reverse extension line of light, such as plane mirror imaging.

What is a virtual image, a virtual image is something that can be seen and cannot be projected onto the screen, and what is a real image, a real image is an image that can be seen and projected onto the screen.

The difference between virtual image and real image is that virtual image can only be seen with the eyes and cannot be projected on a white screen, while a real image can be projected on a white screen.

I come to you, what is the virtual image and what is the real image? Is there any difference between the virtual image and the poor real image of the source reputation? So the imaginary image is fictional, so I think it's imaginary, it's imaginary, so the thought is the person, let me come to you, what is the virtual image and what is the real image?

Is there any difference between an imaginary image and a real image? So the imaginary image is fictional, so I think it's fiction, it's like fiction, so the thought hail skin is the person, it's real.

The fundamental difference between a real image and a virtual image is that the real image can be taken on the light screen, and the image can be formed by using the actual light to converge or become an image, while the virtual image is a reverse extension of the actual light, and the obtained image cannot be undertaken on the light screen.

The virtual image is not the point of convergence of the actual rays, it is simply the intersection of the opposite extension of the reflected rays. The reality is the confluence of actual light.

To put it simply, the intersection of the reverse extension of the light to the long line forms a virtual image, and the intersection of the actual light forms a real image. Guess the vertical return.

The real image is the image of the actual formation of the light, which can be displayed on the gray screen, and the virtual image of the light does not actually meet to form the image, but can be seen with the eye.

All images received on the screen and formed on the screen are real images;

All images that can be received by the screen and formed in the void without missing the gap are all virtual images.

Virtual images are often located on the reverse extension line of the light that returns to the skin and enters the human eye, and what the early sleepy human eye sees against the light is located in the void.

The key point is that the real image is the actual light convergence to form a clever wide guess, the filial piety can be formed on the screen, and the virtual image is the image formed by the intersection of the reverse extension of the light line, it cannot be formed on the screen, but the virtual image can be seen with the eyes.

The virtual image cannot be displayed on the screen, and can only be observed through glass or other optical components. Envy orange.

The virtual avatar and the real image are definitely not the same, and the normal situation is that the two avatars are put together, and the difference is very obvious.

Virtual images can only be presented on mirrors, and real images can be imaged.

In physics, what you learn should be lens imaging, the principle of refraction of light.

The real image can be presented on the light screen, it is formed by the convergence of actual light, which can make the negative sensitive to light, so it is called the real image. The virtual image refers to the light emitted by the object point, which is refracted by the lens, and the intersection point of the reverse extension line of its reflection line is called the virtual image point of the object point, and its set is called the virtual image of the object.

The difference between the two: 1. The imaging principle is different: the image formed by the reconvergence of the light emitted by the object after being reflected or refracted by the optical element is called the real image, which is the intersection point of the actual light.

The reality is all upside down. The light emitted by an object is reflected or refracted by the optical elements and diverged, and the image formed by their intersection after they are extended in the opposite direction is called a virtual image.

2. The way of undertaking is different: the virtual image can be directly undertaken with the eyes, but it cannot be undertaken with the light screen; The real image can be undertaken with a light screen, or directly with the eyes**.

3. Different imaging positions: in reflection imaging, the object and image are on the same side of the mirror, and in refraction imaging, the object image is on the opposite side of the lens; In reflection imaging, the object and image are on the opposite side of the mirror, and in refractive imaging, the object image is on the same side of the lens.

(1) Definitions:

Reality is formed by the convergence of actual light, when the light shines directly into our eyes and allows us to see, and generally speaking, the reality is inverted. For example: imaging of small holes in the straight propagation of light;

An imaginary image is a physical word that, if the beam of light is divergent, is the intersection of the reverse extension of the actual ray. Its rendezvous point is called the "virtual image" of the object. Virtual images cannot be achieved by actual light, so they cannot be taken over by light screens.

2) Can it be displayed on the screen?

The real image can be displayed on a light screen and is formed by actual light.

The virtual image cannot be displayed on a light screen, it is not formed by actual light;

3) Direction: The real image is generally inverted; For example: small hole imaging.

The virtual image is generally the same as the original object, for example: mirror imaging (4) whether the light is concentrated or not.

Reality: Light is generally converging;

Virtual image: Light generally does not converge.

What is the difference between a real image and an imaginary image?

The essential difference between a real image and a virtual image is that the real image is formed by the convergence of actual rays, while the virtual image is formed by the convergence of the reverse extension of the actual rays, and there is no actual light passing through the virtual image. Therefore, the method of distinguishing the real image and the virtual image is also very simple, the best way is to use the light screen to capture, if it can be imaged on the light screen, it is the real image, and vice versa.

It's like the actual light is converging. It can be undertaken with a light screen. Imaginary images can't.

In the first two cases, when the object is outside the focal length of the lens at twice the focal length, the light rays are refracted through the lens and converge on the other side of the lens for imaging. It can be undertaken with a light screen. The object is within one double the focal length and will not abrupt on the other side, but the human eye can still see a magnified image.

That's why it's called an imaginary image.

Reality is formed by the convergence of actual light rays, which can be carried over by a screen.

The virtual image is not formed by the convergence of actual rays, but by the convergence of the reverse extension of the rays passing through the lens, which cannot be presented on the light screen, and therefore cannot be undertaken by the screen.

There are two ways to distinguish between real and virtual images: the first real image can be presented with a light screen, while the virtual image cannot be imaged on the light screen, and the second real image is formed by the collection of actual light, and the virtual image is formed by the reverse extension of the actual light.

If we see the fish in the water and ourselves in the plane mirror, it is an imaginary image; When we see objects around us like tables, other students are real images.

The difference between the real image and the virtual image is as follows: 1. The imaging principle is different, the image formed by the convergence of the light emitted by the Zen Li crack body is the real image, and the image formed by the light divergence after the optical device and the reverse extension and intersection is called the virtual image. 2. The difference in the nature of imaging is that the real image is inverted, and the virtual image is upright.

3. The difference in reception methods: the real image can be seen by the eyes and received by the light screen, while the virtual image can only be seen by the eyes and cannot be received by the light screen. 4. The intersection of the actual rays is a real image, and the intersection of the reverse extension of the actual rays is a virtual image.

5. What can be received or recorded with a light screen or white paper or film is a real image, and what cannot be received or recorded with a light screen or white paper or cannot be recorded with film is a virtual image. The real image is formed by the convergence of the actual rays of light, and it is the light that shines directly into our eyes and allows us to see, and generally speaking, the real image is inverted. For example:

Imaging of small holes in the straight propagation of light. The virtual image is formed by the intersection of the opposite extension lines that reflect or refract light, and it is that we appear to have such an object, but in fact the object does not exist, and generally speaking, the virtual image is upright. For example:

Plane mirror imaging. Illustrative example: Examples of real images:

Image on the negative film of a small hole camera, image on the retina of the eye.
