The angle of minimum deviation for prism of angle `pi//3 is pi//6`. The refractive index of the material of the prism is.

If the angle of minimum deviation is of 60^@ for an equilateral prism , then the refractive index of the material of the prism is

If the angle of minimum deviation is of 60^@ for an equilateral prism , then the refractive index of the material of the prism is

The angle of the prism is A and B if the angle of minimum deviation is (180^(@) - 2A) then the refractive index of the material of the prism is

The angle of the prism is A and B if the angle of minimum deviation is (180^(@) - 2A) then the refractive index of the material of the prism is

The angle of incidence for a ray of light at a refracting surface of a prism is 45^(@) . The angle of prism is 60^(@) . If the ray surface minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are:

The angle of incidence for a ray of light at a refracting surface of a prism is 45^(@) . The angle of prism is 60^(@) . If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are :
