    Say if light enters a more dense medium, refraction occurs. But what happens to the frequency, speed and wavelength of the light? I think wavelength changes, but not sure about the others.

    The frequency is constant.
    The phase velocity of the wave changes.

    By v=f X lambda, velocity changing and frequency constant, wavelength also changes right?
    Thanks

    Wavelength decreases if entering a dense medium and increases if entering a less dense medium.
