Question

A rectangular acrylic sheet of plane mirror is bent such that it acts like a concave mirror

Answer 1

Answer:Yes, by bending the acrylic plane mirror into concave mirror it's focal length changes. Explanation:Plane mirror reflects light, whereas concave mirror converge light at a point. ... Focal length of plane mirror is infinity, when it is bent we can measure it's focal length

Answer 2

Answer:

Yes, it becomes the concave mirror.

Explanation:

When the acrylic sheet of plane mirror is bent it behaves like a concave mirror.

A plane mirror is used to reflect light and the laws of reflection obeys for the plane mirror.

Concave mirror is a type of spherical mirror, it is used to converge the rays of light. It has a particular value of focal length. The focal length of the spherical mirror is half of the radius of curvature of the mirror.
