Question: In the Doppler effect, what happens to the frequency of a sound wave as the source moves towards the observer?

Options:

  1. It decreases
  2. It remains the same
  3. It increases
  4. It becomes zero

Correct Answer: It increases

Solution: 

As the source moves towards the observer, the waves are compressed, leading to an increase in frequency.

Questions & Step-by-Step Solutions

In the Doppler effect, what happens to the frequency of a sound wave as the source moves towards the observer?
  • Doppler Effect – The change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.
  • Wave Compression – As the source of sound moves towards the observer, the sound waves are compressed, resulting in a higher frequency.
