Which of the following describes the Doppler effect?
Correct Answer: The change in frequency of a wave due to the motion of the source or observer.
- Step 1: Understand that waves can be sound waves or light waves.
- Step 2: Know that the Doppler effect happens when the source of the wave is moving.
- Step 3: Realize that if the source moves towards you, the waves get compressed, making the sound higher in pitch or the light bluer.
- Step 4: If the source moves away from you, the waves get stretched, making the sound lower in pitch or the light redder.
- Step 5: Remember that the observer is the person or device detecting the wave.
