A car is moving towards you at a speed of 34m/s34m/s. You hear its horn at a frequency of 1200Hz1200Hz. What is the actual frequency of the horn, if the speed of sound on that day is 320m/s320m/s?

True or False: The Doppler effect also occurs with waves other than sound waves.

How will your perceived frequency change if you move away from a stationary source of sound?

1, frequency will be lower

2. Frequency doubled

3. Frequency tripled

4. Frequency will become hugher

  • When the source of a wave and an observer move either towards or away from each...

    When the source of a wave and an observer move either towards or away from each other the observed frequency of the wave will be different from the frequency at which the wave is emitted. For example, if you are standing by the side of the road and a police car with a siren passes by, the frequency of the sound you hear will be higher when the car is moving towards you and lower when it is moving away...
