waves Flashcards
1
Q
longitudinal and transverse waves
A
- transverse waves- the oscillations are perpendicular to the direction of the energy transfer (shown as a squiggly line in a diagram)
- longitudinal- the oscillations are parallel to the directions of the energy transfer
2
Q
frequency meaning
A
number of waves passing a fixed point per second, measured in hertz (Hz)
3
Q
amplitude meaning
A
maximum displacement that any particle achieves from its undisturbed position in metres (m)
4
Q
wavelength meaning
A
distance from one point on a wave to the equivalent point on the next waves in metres (m)
5
Q
period meaning
A
time taken for one complete oscillation in seconds (s)
6
Q
the more energy, the higher the ______
A
amplitude
7
Q
equation for working out period
A
1
———-
frequency
t=1 divided by f
8
Q
what is wave speed
A
speed of a wave is the speed at which the energy is transferred (or the way the wave moves)
9
Q
equation for wave speed
A
frequency x wavelength
