In my physics class, we are going over the Doppler Effect. Wewere given four different equations for two differentscenarios:
- When the observer is stationary but the source is moving
- When the observer is moving but the source is stationary
I was given a problem where both the observer AND the source aremoving at some velocity. The source is emitting a given frequencywhile traveling at a given velocity. The observer is OBSERVING thatfrequency at a given frequency provided in the problem, but theirvelocity is unknown. Seeing as the source is traveling at aCONSTANT velocity, can I treat it as though the source, relative tothe observer, is stationary, and it is only the observer that ismoving? I was thinking of using the receding observer equation of:f- = (1 - v0/v)*fs , wherev0 is the speed of the observer and v is the velocity ofsound in air, 343 m/s. Would this be correct? Or can I not treatthe source as stationary even though it is moving at a constantvelocity?
Thank you in advance! Please comment if you needclarification.
