waves yr 8 Flashcards
amplitude
the difference between the waves resting position and the furthest point from it
compression
an area of longitudinal wave where the particles are closer together than average
frequency
the number of waves passing a point each second
what is a longitudinal wave
a wave which moves in the same direction as the energy it is transferring
oscillation
regular movement form the resting position which varies in position and magnitude
peak
highest point
perpendicular
occurring at 90 degrees to surface. for example a traverse wave transfers energy at right angles to the direction to which it oscillates
resting position
no waves passing through
transverse
a wave which moves at right angles to the direction of energy transfer
trough
lowest point in a transverse wave
wavelength
the distance from a point on one wave to the equivalent point on an adjacent wave
wave
a means of transferring energy from one store to another
