Question

Trace the path of the reflected ray by drawing a figure if it passes from centre of curvature of a

Concave mirror.

Answer 1

look at attachment

centre of cervature .
actually a mirror or lens is form by cutting of two lens and mid of the center of this glasses is known as center of cervature.



NOW YOUR QUESTION,


Trace the path of the reflected ray by drawing a figure if it passes from centre of curvature of a

Concave mirror.



FOR PATH LOOK AT ATTACHMENT DIGRAM


✺ when light passes through center of cervature then it retrace it path



REASON


✺because as the ray of light passes through centre of curvature of a concave mirror it strikes the mirror along the normal

MORE CLEARTY

 ✺ it incidences on to the mirror at 90 degree. Hence the incident ray coincides with the normal.    Therefore angle of incidence = 0 so, as we know according to law of reflection angle of reflection = 0, hence the angle of reflection too become zero degree, thus ray of light retraces its path.

Answer 2

the incident ray through the centre of curvature of a concave mirror reflects back through the straight line which is coincident with the incident ray
