how can the refractive index of glass change?

Expert Answer:

this is due to the fact that light rays of different color (different wavelength) travel with different speed and hence have different refractive index,

δm = (n-1) / A, where n is the refractive index and δm is the angle of deviation hence different colors will deviate with different angles and dispersion will occur.
