What do convex mirrors and convex lenses do

The convex mirror has a divergent effect on the light, which is formed by the reflection of the light on its surface, and the light does not pass through the convex mirror; Convex lenses have a converging effect on light rays, which are formed by the refraction of light through convex lenses.

Convex mirrors diverge light.

Convex lenses converge light.

1.The structure is different: the structure of the convex mirror is thick on the inside and thin on the edge, while the convex lens is actually similar to the mirror, except that it is designed to look out convex mirror.

2.Effect on light: Different convex lenses mainly refract light, and convex mirrors mainly reflect light.

3.The imaging properties are different: convex lenses are refractive imaging, and convex mirrors are reflection imaging.

A spherical mirror that uses the outside of the parabola as a reflective surface is called a convex good local mirror. Convex mirrors have a divergent effect. Convex mirrors are also called wide-angle lenses, reflective wax lenses, and turning lenses.

It is mainly used for various curves and intersections. It can expand the driver's vision and reputation, detect the opposite vehicle on the curve as early as possible, so as to reduce the occurrence of traffic accidents, and is also used for supermarket anti-theft and monitoring blind spots.

A convex lens is a common type of lens that is thick in the middle and thin at the edges, and at least one surface is spherical, or both sides are spherical. Plays a role of amplification. Multiples vary.

When the object is placed outside the focal point, it becomes an inverted real image on the other side of the convex lens, and there are three types of real images: reduced, equal size, and magnified. The smaller the object distance, the larger the image distance, and the larger the real image. The object is placed in focus, and the virtual image is magnified upright on the same side of the convex lens.

The larger the object distance, the larger the image distance, and the larger the virtual image. No imaging when in focus.

The convex lens has the effect of magnification, which is also what we generally call a magnifying glass, which can be used to see things in the distance, magnify objects, and gather light.

Dear, etc. The convex lens has the effect of converging light in life The use of his farsighted eyes in life Telescope, camera, projector, magnifying glass, microscope, etc. The concave lens is the divergent light The cat's eye on the door is made of this mirror The middle is thick, and the two sides are thin convex lenses; Otherwise, it is a concave lens. Convex lenses are used to magnify images, focus, and make telescopes, microscopes, aging mirrors, etc.

Concave lenses are used for light divergence, shrinking images, and making glasses for myopia. He also participates in the production of microscopes and telescopes. Myopia lenses are convex lenses Reading glasses are concave lenses.

Convex lenses can magnify items, and can also use light to ignite items, reading glasses in life are made with convex lenses, and telescopes and microscopes are made of convex lenses, and some other instruments are available, astronomical telescopes are also available.

Convex lenses can be used to observe many objects and can have a good magnification effect, such as telescopes, microscopes, and some delicate instruments with convex lenses on them.

The role of a convex lens is to concentrate light, and it can also be used to magnify. For example, the magnification and camera lenses we use in our daily life are made with convex lenses.

It is used to concentrate light, which is used by many technologies, and is generally used to set up telescopes or other cameras, which can be used as lenses for cameras or lenses for magnifying glasses, which are of great help.

Although there is only one word difference between convex mirror and convex lens, there is still a big difference between the two. First of all, their shapes are different, the structure of the convex mirror is thick and thin, and the convex lens is actually similar to the mirror, but it is designed to be a convex mirror outside the socks of Wangzaochang. For the convex mirror, it is an instrument made according to the reflection law of light, which is mainly used to expand the field of view, and the virtual image formed by the convex mirror is upright and reduced.

The convex lens uses the principle of light hitting the medium to image, that is, the law of refraction, which can form a virtual image or a real image.

Convex lens and convex mirror I believe many people understand it, lens and mask for daily life has brought a lot of convenience, from the slow and there are many instruments to use these two aspects, but what is the difference between the two This question bothers many people, let's take a look at the difference between convex lens and convex lens.

Speaking of lenses, compared to what many people have known, this slag is a common instrument that can let light pass through, and at the same time use light refraction to image, at this time the light follows the law of refraction. So what is a mask This instrument is not transparent, but reflects imaging, in which the light rays follow the law of reflection. If you look at it this way, you should be able to see the difference.

The convex lens can form a real image or a virtual image of vertical magnification, such as shrinking, inverted, magnifying, etc., and can also converge the parallel light, and then refract the light emitted by the focal point, such as a magnifying glass; Convex mirrors can form a kind of upright and narrowed virtual image, which can mainly expand the field of view, such as the safety mirror of the road surface.

Convex mirrors and convex lenses have different shapes: convex mirrors are thick on the inside and thin on the outside. Convex lenses are similar to mirrors and are flat.

The imaging properties of the two are also different: because the convex mirror uses the principle of light reflection, it forms a virtual image that is upright and shrinking. Convex lenses, on the other hand, use the principle of refraction of light.

However, because it is imaged using a medium, the image formed can be virtual or real.

What are the differences

The convex lens can form a real image of reduction, inversion, magnification, etc., or an upright magnified virtual image, such as a magnifying glass; Convex mirrors can form a kind of upright and narrowed virtual image, which can mainly expand the field of view, such as the safety mirror of the road surface.

Convex lenses

The convex reed mirror is made according to the principle of refraction and judgment of light. Convex lenses are thicker lenses with thinner edges. Convex lenses are divided into the forms of double convex, plano-convex and concave and convex (or positive meniscus), convex lenses have the effect of converging rays, so they are also called converging lenses, and thicker convex lenses are expected to be far away, converging and other effects, which are related to the thickness of the lens.

Farsighted glasses are convex lenses.

Convex mirrors

Convex mirrors are also called wide-angle lenses, reflective lenses, and turning mirrors. It is mainly used for various curves and intersections. It can expand the driver's field of vision, detect the opposite vehicle on the curve early, reduce the occurrence of traffic accidents, and is also used for supermarket theft prevention and monitoring blind spots.

1. The structure is different. A convex lens is made up of two transparent mirrors ground into a spherical surface, and a convex mirror is made up of a convex mirror with one side convex and the other opaque.

2. The effect on the light is different. Convex lenses mainly refract light, and convex mirrors mainly reflect light.

3. The imaging properties are different. Convex lenses are refractive imaging, and convex mirrors are reflection imaging.
