Discuss the below:
Q: A stationary observer hears a frequency of 500Hz while the source is moving directly toward him. If he hears a frequency of 400Hz when the source is moving directly away from him, what is the speed of the source? (assume that the speed of sound is 344 m/s)
Q1: Same question but the frequency are not given but the speed of source moving toward listener is 35 m/s and when source is moving away from observer speed is at 20 m/s. find both frequency's (observer is still stationary)?
Q2: How about if the source is stationary but listener is not and has the same speed as the source did?
Q3: How about if we had the similar question but the observer is not stationary and is moving directly toward the source that has a 500Hz frequency. If he hears a frequency of 400 Hz when he is moving directly away from the source, what is the speed of the observer/listener?
