It may refer to the fact that the mirror does not invert the image.
Inner curved surface is known as concave mirror because inner side of the spherical mirror is polished to reflect the light is called concave mirror,and concave mirror is know because concave mirror converges parallel beam of light.
no concave mirror is in shape of concave mirror
why do we use concave mirror as converging mirror
Focal length, positive number with a concave mirror, negative for a convex mirror.
Yes, a concave mirror can focus light. When light rays reflect off a concave mirror, they can come together at a single point known as the focal point. This can create a focused image.
A concave mirror is a curved mirror that curves inward. In a ray diagram for a concave mirror, parallel rays of light that hit the mirror will converge at a point known as the focal point. One characteristic of the image formed by a concave mirror is that it can be real or virtual depending on the object's distance from the mirror.
The focal length of a concave mirror to form a real image is positive. It is equal to half the radius of curvature (R) of the mirror, and the image is formed between the focal point and the mirror.
Concave
Any ray that travels parallel to the principal axis of a concave mirror will reflect through the mirror's focus after reflection. This is known as the "law of reflection" for concave mirrors.
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light.
Such a mirror is concave.
A concave mirror would focus the light back towards the focal point of the mirror. You would not be able to use the mirror effectively with a concave.
