when a monochromatic beam of light travels from air to glass, it slows down inside glass. the factors affecting speed of light are frequency and wavelength. as frequency remains constant, the wavelength should be changing....... does this mean that the color of the light changes inside the glass??

Dear student,

Refraction is the bending of a wave when it enters a medium where it's speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The amount of bending depends on the indices of refraction of the two media and is described quantitatively by Snell's law.
