Question

if a monochromatic beam of light undergoes minimum deviation through an equiangular prism how does the beam pass through the prism with respect to its base
if white ray is used in same way as in above what change is expected in emergent beam​

Answer 1

A monochromatic beam of light undergoes minimum deviation through an equiangular prism . ... In the case of minimum deviation position, the angle of incidence is equal to the angle emergence. Hence, the beam which passes through the prism is parallel to the base of the prism

When light passes through a prism the light bends. As a result, the different colors that make up white light become separated. This happens because each color has a particular wavelength and each wavelength bends at a different angle.
