The angle of minimum deviation by prism is (180^(0)-2A) .Its critival angle will be

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

For the angle of minimum deviation of a prism to be equal to its refracting angle, the prism must be made of a material whose refractive index

For the angle of minimum deviation of a prism to be equal to its refracting angle, the prism must be made of a material whose refractive index

If the angle of prism is 60^(@) and the angle of minimum deviation is 40^(@) , the angle of refraction will be

If the angle of prism is 60^(@) and the angle of minimum deviation is 40^(@) , the angle of refraction will be
