A ray of light is incident at an angle of 60^(@) on face of a prism of angle 30^(@) The emergent ray makes an angle of 30^(@) with the incident ray. Calculate the refractive index of the material of the prism. |

Answer» SOLUTION :`i_(1)=60^(@), R=30^(@), i_(2)=30^(@)` `MU=(SIN i)/(sin r)` `mu=(sin 0^(@))/(sin 30^(@))` `mu=(sqrt3)/(2xx(1)/(2))` `mu=sqrt3` `mu=1.732` |
