Homework Statement
A man strikes a 460. Hz tuning fork and moves away from you and towards the blackboard at a constant velocity of 3.80 m/s. What beat frequency do you hear if the velocity of sound on that day is 340 m/s?
Homework Equations
The Attempt at a Solution
Since the source is moving away from a stationary observer, we write;
fo= (1/1+Vs/V) * fs
fo= (1/1.011)(460Hz)
fo= 455Hz
SO, fo= 455Hz, fs=460Hz
Now we find the beat frequency, we write;
fbeat= |f1-f2|=5.00Hz (This was wrong)
---> Not sure what I am missing.. please help. Thanks
