Question

The angle of deviation $D$ suffered by a ray of light passing through a prism is the angle

• A. subtended by emergent ray from the incident ray
• B. subtended by emergent ray from the refracted ray
• C. subtended by refracted ray from the incident ray
• D. subtended by incident ray from refracted ray or reflected ray from emergent ray

Answer 1

The correct option is D subtended by incident ray from refracted ray or reflected ray from emergent ray

The angle of deviation $D$ suffered by a ray of light passing through a prism is the angle subtended by incident ray from refracted ray or reflected ray from emergent ray.

Hence, Option $D$ is correct answer.
