Doppler Effect Flashcards
1
Q
Explain the Doppler effect…
A
When something that emits waves that moves towards you or away from you, the wavelengths and frequencies of the waves seem different - compared to when the source of the waves is stationary.
2
Q
Explain the frequencies…
A
The frequency of a source moving towards you will seem higher and its wavelength will seem longer.
The frequency of a source moving from you will seem lower and its wavelength will seem longer.

Q
What waves does the Doppler effect happen at?
A
The Doppler effect happens to both longitudinal waves (e.g. sound) and transverse waves (e.g. light and microwaves).
