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

The light is different.

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.

Imaging principle: The image formed by the reflection or refraction of the light emitted by the object is called the real image, 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.

1. The imaging principle is different: the real image is the image formed by the reconvergence of the light emitted by the object after being reflected or refracted by the optical elements. A virtual image is an image formed by the light emitted by an object that is reflected or refracted by optical elements and diverged, and when they are extended in reverse directions.

2. The way of undertaking is different: the virtual image can be directly undertaken with the eye, 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. Different ways to undertake:

The real image can be displayed on the light screen.

Virtual image. Cannot be rendered on a light screen.

2. Different angles of imaging:

Convex lens imaging.

The reality is all upside down.

The convex lens imaging virtual image is upright.

3. The imaging principle is different:

The actual light rays converge to form the image of reality.

The actual rays of light converge in reverse to form a virtual image.

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

The real image is formed by the convergence of the actual rays, while the virtual image is formed by the convergence of the reverse extension of the positive code of the actual rays, and there is no actual light passing through the virtual image.

The intersection of actual rays forms a real image, and the intersection of the reverse extension lines of actual rays forms a virtual image.

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 film is a virtual image.

The upside-down must be a real image, and the upright must be a virtual image.

If the image and object are on the opposite side of the lens, it is a real image, and if the image and object are on the same side of the lens, it is a virtual image.

An image in which light rays are reflected by a concave mirror or refracted through a convex lens and then converged.

Not only can it be displayed on the screen, but it can also be used to sensitize photographic negatives, which are used for photography or film screening.

The light source is outside the primary focus for the real image.

upright; Formed by the convergence of the reverse extension lines of the actual rays;

Cannot be visualized on a light screen;

It can only be observed through optical elements (glass, etc.);

In the imaging feature of convex lens, the virtual image stool is on the same side of the object.
