A glass prism of angle `72^@` and refractive index 1.66 is immersed in water of refractive index 1.33Find teh angle of minimum deviation for a parallel beam of light passingh through the prism.

What happens when a convex lens of refractive index 1.2 is immersed in a liquid of refractive index 1.3?

A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40^@ . What is the refractive index of the material of the prism? The refracting angle of the prism is 60^@ . If the prism is placed in water (refractive index 1.33), predict the new angle of minimum deviation of a parallel beam of light.

Explain what happens ,when a convex lens of refractive index 1.2 is immersed in a liquid of refractive index 1.3.

Prism of refractive index 1.53 is placed in water of refractive index 1.33.If the angle of the prism is 60^@ ,calculate the angle of minimum deviation in water.

A glass prism is held in water. How is its angle of minimum deviation affected?

A glass of refractive index 1.45 disappears when immersed in a liquid. What is the value of refractive index of the light?

A lens is made of flint glass(refractive index=1.5).When the lens is immersed in a liquid of refractive index 1.25 ,the focal length

A thin prism of angle 15^@ made of glass of refractive index = 1.5 is combined with another prism of glass of refractive index = 1.75 .The combination of prism produces dispersion without deviation.The angle of the second prism should be
