A
amplitudethe maximum displacement or distance from the equilibrium position of a particle or medium as the wave passes through it | |
C
crestThe peak, or highest point, of a transverse wave | |
D
displacementthe change in position of an object or particle from its initial point to its final point | |
E
EM spectrumthe entire range of EM waves in order of increasing frequency and decreasing wavelength. | |
equilibrium positionthe stable resting point of an object or system when there are no external forces acting upon it | |
F
frequencythe number of complete cycles or oscillations it completes in a given time period | |
G
gammareleased by nuclear reactions in nuclear power plants, by nuclear bombs, and by naturally occuring elements on Earth. | |
I
infraredUsed for finding people in the dark and in TV remote control devices. | |
L
longitudinalthe particles of the medium move in a direction parallel to the direction of wave propagation. It's like a wave doing the "forward march," moving in sync with its path as it travels through space. | |
