As the ray of light passes from air to glass , state how the wavelength of light changes does it increase , decrease or remain constant ?

When a light wave travels from air to glass :

When a ray of light enters a glass slab from air

When a ray of light enters a glass slab from air.

A ray of light passes from water to air, How does the speed of light change ?

When a ray of light passes from air to glass, for what angle of incidence, the ray will not be deviated?

A light ray passes from water to (i) air, and (ii) glass. In each case, state how does the speed of light change.

When a ray of light from air enters a denser medium, it :

A monochromatic ray of light passes from air to glass. The wavelength of light in air is lamda , the speed of light in air is c and in glass is V. if the refractive index of glass is 1*5 , write down (a) the relationship between c and V, (b) the wavelength of light in glass.

How does the speed of light in glass change on increasing the wavelength of light?

If each data point in a set is increased by 7, does the set's standard deviation increase, decrease, or remain constant?
