Law of conservation of energy | states that the total energy of an isolated system remains constant |
wavelength | the distance between one peak and the next in a wave, or between one trough and the next |
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 |
law of refraction | compares the angle of incidence to the angle of refraction. |
