Doppler Effect - Moving Source

A wave source, initially at the origin, emits wave fronts with a frequency of 1 and wave length of 1.
  • The source can move to the right with a speed set by the v slider.
  • The wave length and frequency observed in front of and behind the source are shown.
  • The time, t, slider can be adjusted by hand if required.
