NEET Physics Prism MCQ Question
Consider a triangular glass prism ABC with a ray of light entering at angle i and emerging at angle e, as illustrated. If the angle of the prism is A and the refractive index of the material is μ, which equation accurately represents the relationship involving the angle of deviation δ?
δ = i + e - A
δ = i - e + A
δ = A - i - e
δ = A + i + e
Correct Answer
Detailed Explanation
The angle of deviation δ in a prism is given by the formula δ = i + e - A, where i is the angle of incidence, e is the angle of emergence, and A is the angle of the prism.
