    D
    both (A) and (B)

  • The angular dispersion produced by a prism

    A
    increases if the average refractive index increases

    Dispersion Of Light |Prism

    In dispersion of light by a glass prism, yellow colour is deviated the least.

    Find the angular dispersion produced by a thin prism of 5^(@) having refractive index for red light 1.50 and for violet light 1.60

    Dispersive power of the material of prism is 0.0221 . If the deviation produced by it for yellow colour is 38^ @ then the angular dispersion between red and violet colours is

    The angular dispersion produced by a prism of angle 5^@ is [mu_v = 1.665, mu_r = 1.645]
