STANDARD Physics Prism MCQ Question
Type: MCQ-numerical-Medium-Class 12
A monochromatic light is incident at a certain angle on an equilateral triangular prism and suffers minimum deviation. If the refractive index of the material of the prism is √3, then the angle of incidence is
A
60°
B
45°
C
90°
D
30°
Correct Answer
Option A
Detailed Explanation
For minimum deviation, the angle of incidence equals the angle of emergence. Using Snell's law at the interface and the given refractive index, the angle of incidence is calculated to be 60°.
