Physics
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.
Answer
In a prism as well as a parallel sided glass slab the emergent ray is parallel to the incident ray with a lateral displacement .
Reason — In a parallel-sided glass slab, the emergent ray is parallel to the incident ray without any lateral displacement. However, in a prism, there is a lateral displacement of the emergent ray due to the angle of the prism.
