- size of prism

Answer
size of prism
Reason — The deviation produced by the prism depends on :
- the angle of incidence
- the material of prism
- the angle of prism
- the colour or wavelength of light used.
It does not depend on the size of prism.

A ray of light of wavelength 6600 Å suffers refraction from air to glass. Taking aμg = 3/2, find the wavelength of light in glass.
In refraction of light through a prism, the light ray:
- suffers refraction only at one face of the prism
- emerges out from the prism in a direction parallel to the incident ray
- bends at both the surfaces of the prism towards its base
- bends at both the surfaces of prism opposite to its base.
In the figure given ahead the correct statement is:
- ABED and ABC are the refracting surfaces.
- line AD is the refracting edge
- angle a is the angle of deviation
- AB is the base of the prism.
The cross section of the prism is :
- triangular
- square
- rectangular
- parabolic
