Monochromatic light is incident on a glass prism of angle A. If the refractive index of the material of the prism is `mu`, a ray, incident at an angle `theta`, on the face AB would get transmitted through the face AC of the prism provided:

Options

A. `theta gt cos^(-1) [ mu sin (A+sin^(-1) (1/mu))]`
B. `theta lt cos^(-1) [ mu sin (A +sin^(-1) (1/mu))]`
C. `theta le sin^(-1) [mu sin (A-sin^(-1) (1/mu))]`
D. ` theta gt sin^(-1)[ mu sin (A-sin^(-1) (1/mu))]`

Answer

C
