Question

6) A ray of light incident on a concave mirror after passing
through the centre of curvature is reflected back along the
same path. What is the angle of incidence?​

Answer 1

Explanation:

angle of incidence =0

because we know that a ray reflecte back in the same path will only happen when it fall on normal of a plan

$angle \: of \: incidence = angle \: of \: refelection \:$

Answer 2

Answer:

A ray of light passing through the centre of curvature of a concave mirror is reflected back along the same path because it strikes the concave mirror at right angles to its surface due to which the angle of incidence and angle of reflection both aare same....
