A glass prism of angle 60^(@) and mu_(g) = 1.66 is immersed in a liquid of mu_(1) = 1.33. Find the angle of minimum deviation for a parallel beam of light passing through prism. |

Answer» `9.4^(@)` When prism is DIPPED in water and `delta_(m)`is MINIMUM DEVIATION, then `.^(w)mu_(g)=(sin((A+deltam)/(2)))/((sinA)/(2))` ` = (1.66)/(1.33)` Solving, we get, `delta_(m) = 17.2^(@)` |
