SHEET! - WAVES
FREQUENCY AND PERIOD
Frequency = NUMBER OF WAVES PASSING A SINGLE POINT EACH SECOND. MEASURED IN Hertz (Hz)
Hertz means 'per second'.
A period (on waves sheet!) is the time taken for the wace to go from start to finish.
Period = 1/frequency
Frequency = 1/period
THE WAVESPEED EQUATION
Wavespeed is measured in metres per second (m/s)
- Hertz has units of per second (-/s)
- Wavelengh has units of metres (m)
- MULTIPLY BOTH GIVES m/s (wavespeed)
WAVESPEED (m/s) = FREQUENCY (Hz) x WAVELENGH (m)
