A trihedral prism with refracting angle `60^(@)` provides the least deflection angle `37^(@)` in air. Find the least deflection angle of that prism in water.

A prism with an angle A = 60^(@) produces an angle of minimum deviation of 30^(@) . Find the refractive index of material of the prism.

A light ray composed of two monochromatic components passes through a trihedral prism with refracting angle theta = 60^(@) . Find the angle Delta alpha between the components of the ray after its passage through the prism if their respective indies of refraction are equal to 1.515 and 1.520 . the prism is oriented to provide the least deflection angle.

The least deflection angle of a ceratin glass prism is equal to its refracting angle. Find the latter.

A monochromatic ray of light strikes one face of a prism at an angle of 60^(@) and the angle of refraction is 30^(@) . The refracting angle of the prism is 60^(@) . What is the angle of emergence ?

A ray of light is incident at an angle of 60^(@) on the face of a prism with an angle of 60^(@) . Then the refractive index of the material of the prism is (the prism is in minimum deviation position)
