What are concave and convex mirrors collectively called?

It's definitely a spherical mirror, it's wrong to say everything else, these two mirrors don't transmit light at all, how can it be a lens? The answer of the person in front of me is very puzzling to me...

It should be a spherical mirror or lens.

The convex mirror is an upright and shrinking virtual image, while the flat mirror is an upright virtual image of the same size.

A spherical mirror that uses the outside of the parabola as a reflective surface is called a convex alumination mirror; An object with a flat and smooth surface that can be imaged is called a plane mirror.

1. From the point of view of appearance: the convex mirror is convex and the plane mirror is flat;

2. From the perspective of imaging characteristics: the convex mirror is a virtual image that is upright and shrinking; The characteristics of plane mirror imaging are that the plane mirror is an upright and equal size virtual image, the distance between the image and the object to the mirror surface is equal, the connection between the image and the object is perpendicular to the mirror, and the image and the object are symmetrical with respect to the mirror surface.

3. From the perspective of use: convex mirrors are mainly used for various curves, bridges and intersections can expand the driver's field of vision, early detection of vehicles on the opposite side of the curve to reduce the occurrence of traffic accidents, and is also used for supermarket anti-theft and monitoring of dead ends; Plane mirrors are mainly used to change the optical path and expand the field of view.

Summary. Concave mirror: A spherical mirror that uses the inside of the spherical surface as a reflective surface is called a concave mirror. 2. Convex mirror: A spherical mirror that uses the outside of the spherical surface as a reflective surface is called a convex mirror.

Concave mirror: Use the inner side of the spherical surface to make the reflective surface of the spherical mirror and call the friend Wang to make the concave mirror. 2. Convex mirror: The spherical mirror that uses the outside of the spherical surface as the reflective surface is called a convex mirror.

Concave mirror, i.e. a concave parabolic mirror. When the parallel light shines on it, it is concentrated on the focus in front of the mirror through its reflection, the reflective surface is concave, the focus is in front of the mirror, when the light source is on the focus, the light emitted is reflected to form a parallel beam, also called a concave mirror, a converging mirror. Convex mirrors, also known as wide-angle lenses, reflective mirrors, and turning mirrors, refer to spherical mirrors that use the outside of the parabola as a reflective surface.

Convex mirror application: Convex mirror 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.

Luyun concave mirror application: the use of concave mirror to the convergence of light can be used as a companion beam, which can be applied to solar cookers, table lamps, TV satellite antennas, and radars. There are also solar welding machines, medical headlamps, reflecting telescopes, etc.

The convex mirror is composed of two transparent mirror bodies ground into a spherical surface; A concave mirror is made up of a mirror body with one side concave and the other opaque. Convex mirrors mainly play a converging role in light rays; Concave mirrors mainly play a divergent role in light.

1.The structure is different.

1) The convex mirror is composed of two transparent mirror bodies ground into a spherical surface.

2) A concave mirror is composed of a mirror body with a concave surface on one side and opaque on the other.

2.The effect on light is different.

1) Convex mirrors mainly refract light.

2) Concave mirrors mainly reflect light.

3.The nature of the imaging is different.

1) The convex mirror can be used to magnify the virtual image upright, magnify the real image upside down, zoom in the real image upside down, and reduce the real image upside down.

2) The concave mirror can only be upright and narrow the virtual image.

4.The focus is different.

1) The convex mirror has a solid focus and has 2 focal points.

2) The concave mirror has a virtual focus.

5.Different uses.

1) Convex lenses are used for farsighted glasses.

2) Concave lenses are used for myopia glasses.
