A light wave can slow down or speed up when it enters another medium.

Since the speed of wave motion in general depends on characteristics of the environment,
you can always expect the speed of a wave to change as it moves from one medium to
another. In the case of sound, it's the mechanical characteristics that matter, whereas
for light and other electromagnetic waves, the determining characteristics are the
electrical ones.

So the speed of light changes when it enters a different medium. Now, since the product
of (frequency) x (wavelength) is the wave speed, and the frequency can't change, we ...more

When a wave moves from one medium into another, its direction of propagation changes; this is termed refraction. In addition to the transmitted wave continuing from one medium into another, there is also a reflected wave back into the original medium. For example, when your radio is playing music in your room, the sound waves pass through the walls as well as reflect from them. Similarly, some of the light from your lamp passes through the glass of the window in your room, and some also is reflected from the glass. The fractions of the wave intensity (related to the wave amplitude) that reflect and transmit have to do both with the type of the wave and with the materials that make up the media
