Two sources of sound placed close to each other are wmitting progressive waves given by `y_1=4sin600pit` and `y_2=5sin608pit`. An observer located near these two sources of sound will hear:

Two sources of sound placed close to each othe , are emitting progressively waves given by y_1 = 4sin 600 pi t and y_2=5 sin 608 pi t . An observer located near these two source of sound will hear.

The progressive waves produced by two sources of sound placed close to each other are given as y_(1) = 5 sin 300 pi t y_(2) = 10 sin 290 pi t An observer standing near these two sources will observe.
