Waves Flashcards
Travelling wave
Mechanical or electromagnetic
a disturbance that travels out from the source producing it, transferring energy from the source to other places through which it passes
continuous series of identical waves is a
periodic travelling wave
Transverse wave
a wave where the direction of vibration is perpendicular to the direction in which the wave is travelling
Longitudinal wave
a wave where the direction of vibration is parallel to the direction in which the wave is travelling
Crest
top of a wave
Trough
bottom of a wave
Ampitude
Max distance from the undisturbed position
Frequency
number of cycles passing any point per second
Velocity =
Freq by wave length
Reflection
bouncing of waves off an obstacle in their path
