Physics P1 5.2 Measuring waves.

HideShow resource information
What is the amplitude of a wave?
For any wave, its amplitude is the height of the wave crest or the depth of the wave trough, from the position at rest.
1 of 14
What is the frequency of a wave?
For any wave, its frequency is the number of wave crests passing a point in one second.
2 of 14
What is the wavelength of a wave?
For any wave, its wavelength is the distance from one wave crest to the next wave crest. This is the same as the distance from one wave trough to the next wave trough.
3 of 14
How can amplitude determine wave energy?
The greater the amplitude of a wave the more energy it carries.
4 of 14
What is the unit that wave frequency is measured?
Hertz (Hz), this unit is equivalent to per second(s).
5 of 14
What is the equation used to work out the speed of a wave?
v = f x (strange symbol you need to look up).
6 of 14
What does the v mean in the equation for the speed of a wave?
v is the wave speed in metres per second, m/s.
7 of 14
What does the f mean in the equation for the speed of a wave?
f is the frequency in hertz, Hz.
8 of 14
What does the (strange symbol you need to look up) mean in the equation for the speed of a wave?
It is the wavelength in metres, m.
9 of 14
What is he wavelength of a longitudinal wave?
The distance from the middle of one compression to the middle of the next compression, this is the same as the middle of one rarefaction to the middle of the next rarefaction.
10 of 14
What is the frequency of a longitudinal wave?
The number of compressions passing a point in one second.
11 of 14
What is the speed of waves with a frequency of 5 Hz and a wavelength of 2m?
10 m/s.
12 of 14
What is the unit of frequency for waves?
Hertz, Hz.
