The particles compress and refract, passing along the energy. It travels faster in mediums with particles that are more tightly packed eg. moves faster in metal as opposed to wood.
Also, the more dense the air, the faster sound waves travel.
waves BEND when they move from one medium to another.
They normally refract (bend).
refraction
No
Waves may bend if they move from one medium to another.
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.
When light waves are passed from one medium to another, they are . . . refracted. (Bent)

All waves can travel from one place to another as long as they have a medium to travel through. The only waves that do not need a medium are electromagnetic waves. When using the word "transfer" though. Waves transfer energy; waves themselves are not transfered they simply travel.

If your talking about wavelengths, like in light, it might change depending on the medium it moves trough...

diffraction
diffraction
The disturbances in waves are the ones that push the waves. This can be defined as a variation or oscillation that travels though a medium from one point to another.
