| Longitudinal Wave Longitudinal waves move back and forth. Sound waves are longitudinal | Transverse Waves Transverse waves move side to side. Water waves are transverse waves. |
| Refraction Refraction is when light slows down and changes direction when it enters a different material. | Diffraction is where a wave changes shape and direction when it encounters a obstacle. |
| The Doppler effect is when a moving object compresses the wavelength of a sound wave when it is moving in the same direction. | Reflection is returning a wave without absorbing it. The angle of incidence is always equal to the angle of reflection. |
