The diagram shows a mirror system. If after two reflections the image and the object coincide with each other then the value of radius of curvature of the concave mirror is equal to
Text Solution
Verified by ExpertsThe correct answer is:
C
According to condition Ist image must be form by concave mirror, a distance from plane mirror,
Hence, for concave mirror
u = –4a, v = –2a
⇒
