The refractive indices of the material of the prism for red and yellow colour are 1.620 and 1.635 respectively.
Given: nR = 1.620, nY = 1.635, A = 8° To find: i. Angular dispersion (δV – δR) ii. Dispersive power (ω) Formulae: i. δv – δr = A(nV – nR) ii. ω = \(\frac{n_V-n_R}{n_Y-1}\) Calculation: Since, nY = \(\frac{n_V+n_R}{2}\) ∴ nV = 2nY – nR nV = 2 × 1.635...
