1/30 PotU: Waves math

From the Waves on a String packet, we were able to develop the wave equation:

speed = wavelength x frequency

or, using symbols:

s = λ x f

Units for each variable are:

  • speed in m/s
  • wavelength in meters
  • frequency in Hz (‘Hertz’)

Measurements of a wave are shown below.
