At what angle should a ray of light be incident on the face of a prism of refracting angle 60^(@), so that it just suffers total internal reflection at the other face ? The refractive index of the prism is 1.524. As μ=1sinC and from Fig. ∴sini1=,1.524sin19∘=1.524×0.3256=0.4962∴i1=sin-1(0.4962)=29∘45′.
