Question
Write a relation for the angle of deviation (δ) for a ray of light passing through an equilateral prism in terms of the angle of incidence (i) angle of emergence (ℯ) and angle of prism(A).
✓
Answer
The relation between the angle of incident (i), angle of emergence (e), angle of prism (A) and angle of deviation (δ) for a ray of light passing through an equilateral prism is
δ = (i+e) – A
δ = (i+e) – A
