A ray of light is incident normally on the face of an equilateral glass prism. The angle of refraction from the first face of prism is :
- 45°
- 90°
- 60°
- 0°
Assertion (A): If the angles of the base of a prism are equal, then in the position of minimum deviation, the refracted ray will pass parallely to the base of the prism.
Reason (R): For minimum deviation, angle of incidence is equal to the angle of emergence.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true and R is not the correct explanation of A.
- assertion is false but reason is true.
- assertion is true but reason is false.
State whether the following statement is 'true' or 'false'.
The deviation produced by a prism is independent of the angle of incidence and is same for all the colours of light.
How does the angle of minimum deviation produced by a prism change with increase in (i) the wavelength of incident light and (ii) the refracting angle of the prism?
