Question
When the refractive index of the surrounding medium is decreased, the angle of deviation _____.
- Decreases
- Increases
- Stays the same
- Becomes zero
Hint:
For a given angle of incidence, the prism with a higher refractive index (e.g. flight glass) produces a greater deviation than the prism which has lower refractive index (e.g, crown glass).
The correct answer is: Increases
For a given angle of incidence, the prism with a higher refractive index (e.g. flight glass) produces a greater deviation than the prism which has lower refractive index (e.g, crown glass).
