NEET Physics Reflection MCQ Question

Type: MCQ-diagram based-Hard-Class 12

Consider a concave mirror with a principal axis and a point M on the mirror. A perpendicular is drawn from M to the principal axis meeting it at point P. If MD is a segment on the line MP, and the angles MCP and MFP are represented as q and 2q respectively, which of the following represents the correct relationship between the distances FD and CD?

Question diagram
A

FD = CD/2

B

FD = 2CD

C

FD = CD

D

FD = 3CD

Correct Answer

Option A

Detailed Explanation

The NCERT context describes that for small angles q, tan q approximately equals q, and similarly for 2q. This leads to the relationship FD = CD/2, as derived in the provided equations.
