Speed of light DOES change depending on the medium and this can be seen using the equation:

v=cn

Where v is the velocity of light in the medium, c (~3.0x108 m/s) is the speed of light in vacuum, and n is the index of refraction of the medium.

The higher the index of refraction is, the slower light travels in the medium.
