Wave Properties Flashcards
amplitude
max distance wave moves from rest position
amplitude in transverse waves
max distance particle moves from rest position to crest/trough
amplitude in longitudinal waves
distance between particles in compressions and rarefactions
energy increases as amplitude…
increases
high amplitude in longitudinal =
compressions are close, rarefactions are far
low amplitude =
compressions are farther, rarefactions are closer (comparing w high amplitude)
wavelength
shortest distance from one point of a wave to the same point in the next wave
measuring wavelength in transverse waves
1.) measure distance from one crest to the next
OR
2.) measure distance from one trough to the next
measuring wavelenth in longitudinal waves
1.) measure distance from one compression to the next
OR
2.) measure distance form one rarefaction to the next
remember to measure from the same point
frequency
the # of wavelengths that pass by a point each second
frequency SI unit
Hertz (Hz)
frequency formula
freq. = wv. length divided by time (sec)
as wave length decreases, energy…
increases
speed is affected by….
medium
mechanical waves travel fastest in…
high temperature mediums
