A ray is incident at an angle of incidence i on one surface of a prism of small angle A and emerge normally from opposite surface. If the refractive index of the material of prism is mue the angle of incidence i is nearly equal to(A) A/mue (B)A/2mue(C)mueA (D)mueA/2
Dear student,From geometry, the angle of refraction from the first surface in this case will be equal to the prism angle as shown in figure.From Snell’s law,Sinceis small,
