Question
A light rays is incident upon a prism minimum deviation position and suffers a deviation of 34°. If the shaded half of the prism is knocked off, the ray will
- Suffer a deviation of 34°
- Suffer a deviation of 68°
- Suffer a deviation of 17°
- Not come out of the prism
The correct answer is: Suffer a deviation of 17°
