Waves Flashcards
A repeating disturbance that transfers energy through matter and space (medium)
Wave
Matter and space that waves travel through
Medium
High points
Crest
Low points
Trough
Where wave hits rest position
Node
Line in middle of crest and trough
Rest Position
Distance from resting position
Amplitude
The distance from the top of one crest to the top of the next crest
Wavelength
motion of the medium is at right angles to the direction of travel (opposite of each other)
Transverse Wave
Particles move along the direction of the wave
Longitudinal aka Compression Wave
Dense region of compressional waves
Compression
Less dense region of compressional waves
Rarefaction
The # of times a wave passes one point in one second
Frequency
Energy carried by vibration of matter and formed by “compression” and “rarefraction” of the medium
Sound
Amount of energy that flows through a certain area
Intensity
