Wave Equations

1. Speed, Frequency and Wavelength V= F X

   • V = Wave speed (metres per second, m/s) F = Frequency (hertz, Hz) = Wavelength (metres, m)

2. Speed, Distance and Time V = X/T

   • V = Wave speed (metres/second, m/s) X = Distance (metres, m) T = Time (seconds, s)

3. Example A seismic wave has a frequency of 15 Hz and travels at 4050 m/s. Calculate it's wavelength

   • Start with the equation V = F X and rearrange it to make the subject. Divide both sides of the equation by F, to get = Substitute the values for V and F to calculate the value for the wavelength, . The units for V are m/s and the units for F are Hz (or per second) , so the units for are = m..
