Would the Doppler Effect still apply in an observers reference frame if the observer would be the one moving past the ambulance instead of the ambulance moving (relative to the air)?

Question

Would the Doppler Effect still apply in an observers reference frame if the observer would be the one moving past the ambulance instead of the ambulance moving (relative to the air)?

In: Physics

Answer 1

The Doppler effect applies to any wave, including light.

Light doesn’t have a universal reference frame (no equivalent of the air).
