19 The diagram below shows wavefronts produced by a stationary wave
source S. The spacing of the wavefronts is equal to the wavelength of the
waves. The wavefronts travel with speed V.
The source S now moves to the right with speed V. In the space below,
draw four successive wavefronts to show the pattern of waves produced
by the moving source.
