Across
  1. 3. unit of frequency, equivalent to one cycle per second
  2. 4. effect, an apparent shift in the frequency of a wave due to relative motion between the source of the wave and the observer
  3. 7. where distance x in smaller than distance L
Down
  1. 1. the first wave in a harmonic
  2. 2. wave, A wave in which the particles oscillate in the same direction as the direction of movement of the wave
  3. 5. when two sets of waves have slightly different frequencies
  4. 6. number of waves which reach an observer in one second
  5. 8. a point of maximum amplitude because of constructive interference of waves
