Waves Vocab Flashcards
Compression
The part of a longitudinal wave where the particles of the medium are close together.
Crest
Highest point of a wave
electromagnetic serum
A form of energy that can move through the vacuum of space.
longitudinal wave
the particles of the medium vibrate parallel to the direction of wave motion
Medium
a material in which a wave travels
rarefraction
An area where the particles in a medium are spread out
transverse wave
A wave in which the vibration is at right angles to the direction in which the wave is traveling.
Trough
The lowest point of a wave
amplitude
Height of the wave
frequency
How many waves can pass a given point per second, measured in Hertz
wavelength
Distance between one point on a wave and the nearest point just like it
diffraction
A change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening
reflection
the bouncing of a wave off a surface
refraction
the change of in direction of a wave as it change speed
