Answer:

True

Explanation:

Doppler's effect is the apparent change in the wavelength and frequency of a wave as it moves towards or away from an observer.

  • The relative motion between the observer and the source causes changes to the wavelength and frequency.
  • This effect is the doppler's effect.
  • When a source moves closer, the frequency of the wave increases.
  • For example, we see that effect of water ripples when a stone is dropped in still water.
