Question

A fine beam of white light is
incident upon the longer side of a plane parallel
glass slab of breadth 5 cm at angle of incidence
60°. Calculate lateral deviation of red and violet
rays and lateral dispersion between them as
they emerge from the opposite side. Refractive
indices of the glass for red and violet are 1.51
and 1.53 respectively.​
