1. The problem statement, all variables and given/known data A source of sound waves of frequency 1.0 kHz is traveling through the air at 0.50 times the speed of sound. (a) Find the frequency of the sound received by a stationary observer if the source moves towards her. (b) Repeat if the source moves away from her instead. 2. Relevant equations v=0.5V F01 = fs/1-(vs/v) F02 = fs/1+(vs/v) 3. The attempt at a solution I tried plugging in the values that are given to me, but I simply don't obtain the correct results. Please help? Thanks in advance.
