Question
The following is a question on waves. I know how wave collide and add together but I can seem to apply it to tis problem.
A large church has two identical organs, one at the front and one at the back. While both organs are playing, a listener walks from the front of the church to the back of the church very quickly. During the walk, he notices that the organs sound out of tune. Why is this?
I think the organs sound out of tune because the sound waves are coliding and thus changing as the listener walks by but im not sure. Im dure theres a better explaination.
Explanation / Answer
AS given in question one organ at back and one at front. it is obvious that both are sounding in opposite direction,. if a person moving near to church it is happen due to doppler effect. and they collides in better way you can say when they supper impose on each other when one is out of phase. then net wave amplitude is zero because both are similar wave
