STANDARD Physics Prism MCQ Question
A ray of light passes through an equilateral prism (refractive index 1.5) such that angle of incidence is equal to angle of emergence and the later is equal to 3/4th of the angle of prism. The angle of deviation is
60°
30°
45°
120°
Correct Answer
Detailed Explanation
For an equilateral prism, the angle of deviation δ is given by δ = i + e - A. Given that i = e and e = 3/4 A, substituting these values gives δ = 30°.
