What are the similarities between concave and convex mirrors?

Similarities between lenses and mirrors The equations we used for mirrors all work for lenses. A convex lens acts a lot like a concave mirror. Both converge parallel rays to a focal point, have positive focal lengths, and form images with similar characteristics. A concave lens acts a lot like a convex mirror.

Why are torches used in concave mirrors?

A concave mirror is used in torch lights , because the light ray from the source placed on the focus of a concave mirror are reflected in such a way that the reflected ray are strong, straight,and parallel.

What is concave and convex mirror?

What are convex and concave mirrors? If the inner side of the spherical mirror is reflecting, it is called a concave mirror. If the outer side of the spherical mirror is reflecting, it is called a convex mirror. Image. Concave mirrors can form inverted and real images and also virtual and erect images.

What is called a spherical mirror?

A spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface. There are two types of spherical mirrors: concave, and convex. … The most commonly occurring examples of concave mirrors are shaving mirrors and makeup mirrors.

What is meant by concave mirror?

Concave mirrors A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light.
