wave types Flashcards
in a wave energy is transferred
from one place to another
in a wave there is no net transfer of
matter
in a wave what does the displacement do
it oscillates
in a wave the displacement could be a
-physical movement of a particle
-the change of another quantity
in a wave oscillations occur around a mean..
rest value of the displacement
in a wave ,displacement is a
vector
with the direction of propagation the line along which the wave energy travels and in which the oscillations move and the wave programmes what do they do
reproduce the pattern of the wave
what are the oscillations in a longitudinal wave
back and forth along the direction of propagation
what are the oscillations in a transverse wave
at right angles to the direction of propagation (up nd down or side to side)
in longitudinal waves what do the oscillations cause
compressions and rarefractions
what are compressions
regions with particles close together
what is rare fraction
when particles are further apart
eg fr longitudinal wave
ultrasound
give an example for transverse waves
water ripples, stretched strings
detectors for transverse waves must be aligned at right angles to the
direction of propagation
