Waves may bend if they move from one medium to another.
Because the wave's velocity changes as it changes from one medium into the other.
The speed of the wave in the different mediums.
When waves travel from one point to another energy is transferred through the medium. Waves are periodic vibrations or oscillations in a medium that propagate through the medium carrying energy in the form of the movement. Exceptions to this are light and gravity waves, which do not require a medium for propagation.
the vibration of the particles of medium of the sound waves causes the sound waves to travel
Refraction is when they change direction slightly when entering the second medium, e.g. flashlight shining down towards water surface

The light bends when it passes from one medium to another. But only if it approaches the interface at an angle. In such a case it will still travel slower, but there will be no apparent bending.
