Two prisms of identical geometrical shape are combined with their refracting angles oppositely directed. The materials of the prisms have refractive indices 1.52 and 1.62 for violet light. A violet ray is deviated by 1.0^@ when passes symmetrically through this combination. What is the angle of the prisms ? |

Answer» `Ler A=angle of the prisms `mu_y=1.52 and mu_y=1.62` `mu_y=1.0^@` `delta_y=(mu_y-1)A-(mu_y-1)A` [since A=a] `delta_y=(mu_y-mu_y)A` `A=delta_y/(mu_y=mu_y)=1/((1.62)-(1.52))` `=1/0.1=10^@` |
