Question

why does a ray of light passing through the centre of curvature of a concave mirror gets reflected along same path after reflection????????​

Answer 1

Answer: This may help you

Explanation:

The reason why light falling on the center of curvature gets reflected back along the same path is because the angle of incidence and the angle of reflection are along the normal for a concave mirror.

This is because if a tangent is drawn at the point of contact of the mirror where the ray passes through the curvature and touches the mirror, then it would be 90 degrees since the radius of curvature is perpendicular to the tangent hence the angle of incidence will coincide with the normal. Therefore angle of reflection will also coincide and hence it passes again through the center of curvature.

Answer 2

Answer:

As the angle of reflection is 0, and the factors involving reflection are purely coincidental. So, roughly speaking, the beam passes through to come out the same as before due to the way it is placed in and this affects it's after affect.
