Question

Explain why a ray of light passing through center of curvature of a concave mirror,gets reflected along same path ?

Answer 1

Because the normal of the concave mirror at every point passes through centre of curvature.
Hence any light rays coming perpendicular to the surface that is making 0 degree with normal retraces the same path.


Hope u got that

Answer 2

Answer:

• The ray of light passing through the center of curvature of a concave mirror gets reflected along the same path because it strikes the surface of the mirror at the normal.
• The incident ray coincides the normal and the angle of incidence becomes 0 degree.
• As we know that, the angle of incidence = the angle of reflection so, angle of reflection = 0 degree.
• Hence, being 0 degree the ray is not reflected and it moves along the same path.
