If this is a sound wave, the denser the medium, the faster the wave. For a light wave, the denser the medium, the slower the wave. It all depends on the medium through which it travels. The factor of the medium that plays a role on the velocity of a wave is its density. If this is a sound wave, the denser the medium, the faster the wave.
