Two loudspeakers face each other at opposite ends of a long corridor. They are connected to the same sourrce that produces a pure tone of 343Hz. A person walks from one speaker towards the other at a speed of 0.7ms-1
What beat frequency does the person hear?
speed of sound= 343ms-1
The Attempt at a Solution
I know the beat frequency equals the frequency of one take the frequency of the second. So if this is right does that mean it is 343 minus the second frequency. Can someone pleasae tell me if this is correct and any hints on how to work out the second frequency please. Thankyou
