Mention the incorrect statement:
- The angle of deviation produced by a prism depends on the colour or wavelength of the light used.
- The angle of incidence also affects the angle of deviation produced by the prism.
- In a prism as well as a parallel sided glass slab the emergent ray is parallel to the incident ray with a lateral displacement.
- The angle of deviation of prism is also affected by the material of the prism.
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°
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?
