The refractive index of a medium with respect to air is `sqrt2`. If the angle of incidence of a ray of light in air is `45^@` determine the angle of deviation for that ray in case of refraction.

The refracting angle of a glass prism is 60^(@) and the refractive index of glass is 1.6. If the angle of incidence of a ray of light on the first refracting surface is 45^(@) Calculate the angle of deviation of the ray . Given that sin 26^(@)14' = 0.4419, " " sin33^(@)46' = 0.5558 and sin62^(@)47' = 0.8893

The refracting angle of a prism is 60^(@) and the refractive index of its material is sqrt((7)/(3)). Find the minimum angle of incidence of a ray of light falling on one refracting face of the prism such that the emerging ray will graze the other refracting face.

Establish the relation among deviation of a ray, angle of incidence and angle of refraction.

The refractive index of a prism having refracting angle 75^(@) is sqrt2 . What should be the minimum angle of incidence on a refracting surface so that the ray will emerge from the other refracting surface of the prism?

When a ray of light is incident on a plane normally, then what is the value of angle of refractive?

The refractive index of the material of a prism is sqrt(2) and the angle of minimum deviation is 30^(@) . Calculate the value of the refracting angle of the prism.

The refractive index of a prism is sqrt(2) and its refractive angle is 60^(@) . If a ray emerge with the minimum angle of deviation then the angle of incidence will be
