Question

If yellow light is refracted at angle of minimum deviation from prism, then:

• A. Angle of incidence and angle of emergence are equal
• B. The sum of the angle of incidence and angle of emergence is ${90}^{\circ }$
• C. Angle of incidence is less than angle of emergence
• D. Angle of incidence is greater than angle of emergence

Answer 1

Answer: (A)

Angle of incidence and angle of emergence are equal

At minimum deviation, the angle of incidence and angle of emergence are equal.
