Question

a light ray passing through the center of curvature retraces its path after reflection. why?

Answer 1

==============================
In a spherical mirror either concave or convex, the Normal of the mirror lie along the Radius of the mirror that is the line joining the point on a mirror and centre of curvature. If a ray of light passes through centre of curvature then the angle of incidence that is angle between incident ray and the normal become zero, and according to second law of reflection "angle of incidence=angle of reflection" the incidence ray also makes a 0° angle with the normal and hence the reflected ray retraces the same prath.

Answer 2

Explanation:-

Any ray of light passes through centre of curvature retraces it's path because the surface of mirror is perpendicular (normal) to that ray and the angle of reflection will be 0.

As we know that according to 2nd law of reflection, angle of incidence must be equal to angle of reflection. The ray of light falling on surface of mirror will deviate at angle of 0° which would be same like that of incident ray.

Hence the ray of light passes through centre of curvature retraces it's path.
