Question: If a sound source moves towards an observer, what effect does it have on the frequency heard by the observer?

Options:

  1. Decreases
  2. Increases
  3. Remains the same
  4. Becomes zero

Correct Answer: Increases

Solution: 

The frequency increases due to the Doppler effect when the source moves towards the observer.

Questions & Step-by-Step Solutions

If a sound source moves towards an observer, what effect does it have on the frequency heard by the observer?
  • Step 1: Understand that sound travels in waves.
  • Step 2: Know that frequency is how many waves pass a point in one second.
  • Step 3: When a sound source moves towards you, it compresses the sound waves in front of it.
  • Step 4: This compression means more waves reach you in the same amount of time.
  • Step 5: Because more waves reach you, the frequency of the sound you hear increases.
  • Step 6: This phenomenon is called the Doppler effect.
  • Doppler Effect – The change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.
