Question

light from the sun falling on a concave mirror will coverage at a point called​

Answer 1

Answer:

Light from the Sun falling on convex lens will converge at a point called as principal focus.

Explanation:

A ray of light passing through a prism bends towards its base.

Answer 2

The point is called FOCUS.

• The sun is a source situated at infinity.

• So, the light rays originating from the sun can be considered as paraxial rays for the concave mirror.

• The paraxial light rays are incident on the concave mirror and get reflected to converge at the focus.

• The distance between the the pole of the mirror and the focus will hence be called as FOCAL LENGTH.
