Question

4. Figure shows a part of prism refractive index 1.5. The incident ray suffers from
minimum deviation.
(a) The angle of refraction at the surface AB is 30°
(b) The refracting angle of prism is 60
(c) Total internal reflection takes place at surface DC
(d) Minimum deviation is not calculated without knowing the angle of incidence
