What is dispersion ?

(i) Plot a graph to show variation of the angle of deviation as function of angle of incidence for light passing through a prism. Derive an expression for refractive index of the prism in terms of angle of minimum deviation and angles of prism. (ii) What is dispersion of light ? Why is its cause ? (iii) A ray of light incident normally on one face of a right isosceles prism is totally reflected as shown in fig . what must be the minimum value of refractive index of glass ? Give relevant calculations
