Term | Definition |
---|---|
Law of conservation of energy | a law that states that energy is conserved in a closed system |
wavelength | the distance between one peak and the next in a wave, or between one trough and the next |
amplitude | the maximum displacement of a wave from its rest position; "strength" of a wave |
frequency | the number of waves that pass a given point during a specified 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 amount of space that an object occupies, measured in liters or centimeters cubed |
pitch | the amount of space that an object occupies, measured in liters or centimeters cubed |
electromagnetic wave | a wave that can transport its energy through a vacuum |
conduction | the transfer of heat energy within an object, or between objects that are directly touching each other, due to collisions between the particles in the objects |
convection | the transfer of heat from one place to another caused by movement of molecules |
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. |
