|
a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium
|
wave
|
|
|
a physical enviorment in which phenomena coour
|
medium
|
|
|
a wave that requires a medium through which to travel
|
mechanical wave
|
|
|
a wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light
|
electromagnetic wave
|
|
|
a wave in which the particles of the medium move perpendicular to the direction the wave is traveling
|
transverse wave
|
|
|
a wave in which the particles of the medium vibrate parallel to the direction of wave motion
|
longitudinal wave
|
|
|
the highest point of the wave
|
crest
|
|
|
the lowest point of the wave
|
trough
|
|
|
the maximum distance that the particles of a wave's medium vibrate from the rest position
|
amplitude
|
|
|
the distance from any point on a wave to an identical point on the next wave
|
wavelength
|
|
|
the time that it takes a complete cycle or wave oscillation to occur
|
period
|
|
|
the number of cycles or vibrations per unit of time
|
frequency
|
|
|
an observed change in the frequency of a wave when the source or observer is moving
|
Doppler effect
|
|
|
the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through
|
reflection
|
|
|
a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening
|
diffraction
|
|
|
the bending of a wavefront as the wavefront passes between two substances in which the speed of a wave differs
|
refraction
|
|
|
the combination of two or more waves of the same frequency that results in a single wave
|
interference
|
|
|
any interference in which waves combine so that the resulting wave is bigger than the original waves
|
constructive interference
|
|
|
any interference in which waves combine so that the resulting wave is smaller than the largest of the original waves
|
destructive interference
|
|
|
a pattern of vibration that simulates a wave that is standing still
|
standing wave
|
