Answer
line AD is the refracting edge
Reason — ABED and ACFD are the refracting surfaces, angle a is the angle of prism and BCFE is the base of the prism.

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.
A ray of light suffers refraction through an equilateral prism. The deviation produced by the prism does not depend on the:
- angle of incidence
- colour of light
- material of prism
- size of prism
The cross section of the prism is :
- triangular
- square
- rectangular
- parabolic
The angle of prism A is given as:
- r1 - r2
- i1 + i2
- r1 + r2
- r1 / r2
