This is the bending of light as it passes from one medium to another, like from air into water.

What is refraction?

100
The high point of a transverse wave
crest
200
Which type of wave moves matter in right angles in the direction of the wave?
Transverse Wave.

The matter that mechanical waves travel through is known as ____________.
Medium
300
The measure of how high or low a wave is
Amplitude
300

When light slows down and bends entering a denser medium, this property of the material determines how much it bends.
