उत्तर
The coloured light having the maximum speed in glass prism is yellow.
Explanation:
Yellow is the coloured light with the maximum speed in a glass prism as it has the greatest wavelength.

Critical angle
The angle of deviation through a prism is minimum when
- Incident rays and emergent rays are symmetric to the prism.
- The refracted ray inside the prism becomes parallel to its base.
- The angle of incidence is equal to that of the angle of emergence.
- When the angle of emergence has doubled the angle of incidence.
