Explain refractive index using water.

Explain refractive index using a plane glass slab.

The ratio of velocities of light in glass that in waters is ( refractive index of glass = 1.5 and refractive index of water = 1. 33)

What is the refractive index of water?

If the refractive index of a certain glass with respect to water is 1.25, find the refractive index of water with respect to the glass.

Assertion : A concave mirror and convex lens both have the same focal length in air. When they are submerged in water, they will have same focal length. Reason refractive index of water is smaller than be refractive index of air.

Complete the analogy : Refractive index of water:1.33: : Refractive index of air:___

The refractive index of a piece of glass of 1.5 and it accommodates as many waves as are accommodated in 18 cm width of water column.If the refractive index of water 1.33 then the thickness of glass piece will be-

Refractive index of kerosene

When the same monochromatic ray of light travels through glass slab and through water, the number of waves in glass slab of thickness 6 cm is same as in water column of height 7 cm. If refractive index of glass is 1.5 , then refractive index of water is

Monochromatic light of wavelength 589 nm is incident from air on a water surface. What are the wavelengths ,frequency and speed of refracted light ? Refractive index of water is 1.33
