|
A periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium.
|
wave
|
|
|
a physical environment in which a phenomena occur.
|
medium
|
|
|
a wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light.
|
electromagnetic wave
|
|
|
a wave that requires a medium through which to travel.
|
Mechanical 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 a wave.
|
Crest
|
|
|
The lowest point of a wave.
|
Trough
|
|
|
the maximum distance that the particles of a wave's medium vibrate form their resting 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 wave as it passes between two substances in which the speed of the wave differs.
|
Refraction
|
|
|
Combination of 2 or more waves of the same frequency that results in a single wave.
|
Interference
|
