Frequency of light depends only upon source. It is independent of all other factors. Hence frequency of light does not change when it enters into a different medium.
Velocity of light depends on the medium. It is less in a denser medium and more in the rarer medium. We have the relation, velocity = (Frequency) (Wavelength).Since freq. remains unchanged; Wavelength undergoes the same changes as Velocity.
