What happens to the observed wavelength if the source of a wave travels toward an observer?

Sagot :

If the observer and source are moving toward each other, then the frequency increases and the wavelength decreases.

What is dopper effect?

  • The Doppler effect defines the shift in frequency of a wave sound caused by movement of the wave source and/or receiver. We'll talk about it in terms of sound waves, but the Doppler effect applies to any type of wave.
  • The Doppler effect, like ultrasound, has a wide range of uses, from medical (with sound) to police radar and astronomy (with electromagnetic waves).
  • The Doppler effect happens when there is relative motion between the observer and the source, not just for sound.
  • Doppler shifts, for example, occur in the frequency of sound, light, and water waves. When ultrasonography is reflected from blood in a medical diagnosis, Doppler shifts can be utilized to assess velocity.
