प्रश्न
If a spherical mirror breaks, what type of mirrors are the individual pieces?
Advertisements
उत्तर
After the breakdown of the spherical mirror, each piece of the mirror is the same type of original mirror (concave/convex), as the reflective background and curvature have no differences in radius.

AB is the object, A1B1 is its image. MM' is the position of the mirror. Complete the ray diagram and find the position of the center of curvature and focus of the mirror. Also, measure the focal length.
Assertion: Incident ray is directed towards the centre of curvature of spherical mirror. After reflection it retraces its path.
Reason: Angle of incidence (i) = Angle of reflection (r) = 0°
