Question
A light ray passed through the center of curvature of a concave mirror and reflected back along the same path. The angle of incidence, in this case is ____ degrees.
Hint:
0
The correct answer is: 0
the ray of light passes through the centre of curvature of a concave mirror it strikes the mirror along the normal ray, it incidences on to the mirror at an angle of 90°. Hence, the incidsnt ray coincides with the normal.
Therefore, angle of incidence=0
