Monochromatic light of yellow colour is incident on a face of a prism. Refractive index of prism for yellow colour is a//2 . It is observed that for two different values of angle of incidence, 60^(@) and 32.3^(@), deviation suffered by the ray while passing through the prism has the same value of 8=32.3^(@). Consider now that white light is incident on a face of the % given prism at an angle of incidence (i). Obviously it will undergo dispersion. Match Column-I w.ith Column-ll with regard to dispersion of white light as it passes through the prism. [sin20^(@) = 0.34, sin 14^(@) = 0.24] |
