While studying the Doppler effect at school, it struck me as strange that the following two problems have different solutions:
a) you are moving at 40 m/s toward a source that is making a sound with a frequency of 1000 Hz. What frequency do you hear? (speed of sound= 340 m/s)
b) The source of a sound is moving toward you at 40 m/s, producing a sound with a frequency of 1000 Hz. What frequency do you hear? (speed of sound = 340m/s)
I thought that they would both have the same observed frequency, but they don't. Could someone explain why?
