| amplitude | height or "strength" of a wave |
| frequency | the number of cycles a wave completes in a period of time; the number of times something happens in a period of time |
| reflection | a change in the direction of a wave when it hits a barrier and bounces back |
| refraction | a change in the direction and velocity which occurs when a seismic or electromagnetic wave travels from one material into another of different density, state, or elasticity |
| volume | the loudness or softness of a sound that you hear |
| pitch | the perceived frequency of a sound wave |
| electromagnetic wave | a wave that can transport its energy through a vacuum |
| conduction | a wave that can transport its energy through a vacuum |
| convection | the transfer of heat through a fluid |
| radiation | a process by which energetic electromagnetic waves move from one place to another |
| law of reflection | specifies that the angle of incidence is equal to the angle of reflection |
