Question

Source and observer both start moving simultaneously from origin one along $$x-axis$$ an the other along $$y-axis$$ with speed of source $$=$$ $$2$$ (speed$$ of $$observer). The graph between the apparent frequency observed by observer (f) and time (t) would be: (Here$$, $$f0$$ $$=$$ natural frequency of $$source)  (dotted$$ line indicates the original $$frequency)

At any instant,So, apparent frequency does not change with time. as they are going apart the apparent frequency is less than original frequency
