The refractive index of a material is `sqrt3`. What is the angle of refraction if the unpolarised light is incident on it at the polarising angle of the medium.

Refractive index of a maerial is equal to tangent of polarising angle.It is called

What is the value of refractive index of a medium of polarising angle 60^@ ?

What is the speed of light in a dense medium of polarising angle 30^@ ?

The refractive index of a material of a concave lens is n_1 . It is immersed in medium of refractive index n_2 . A parallel beam of light if incident on the lens. Trace the path of the emergent lays when n_2 = n_1

The refractive index of a material of a concave lens is n_1 . It is immersed in medium of refractive index n_2 . A parallel beam of light if incident on the lens. Trace the path of the emergent lays when n_2 > n_1

The refractive index of a material of a concave lens is n_1 . It is immersed in medium of refractive index n_2 . A parallel beam of light if incident on the lens. Trace the path of the emergent lays when n_2 < n_1 .

The refracting angle of a prism is A and the refractive index of its material is cot A//2 .For a ray of light incident on the prism,find the angle of minimum deviation in terms of A.

The refractig angle of a prism is A and the refractive index of its material is mu .When a ray of light is incident on the face AB of the prism,after refraction through the prism,the ray of light just grazes along the face AC as shown in Fig.3.21. Determine the value of the angle of incidence in terms of A and mu .
