A stationary detector measures the frequency of a sound source that first moves at constant velocity directly
Question:
A stationary detector measures the frequency of a sound source that first moves at constant velocity directly toward the detector and then (after passing the detector) directly away from it. The emitted frequency is f. During the approach the detected frequency is f’app and during the recession it is f’rec. If (f’app – f’rec)/f = 0.500, what is the ratio vs/v of the speed of the source to the speed of sound?

I have done job as Embedded System Engineer for just four months but after it i have decided to open my own lab and to work on projects that i can launch my own product in market. I work on different softwares like Proteus, Mikroc to program Embedded Systems. My basic work is on Embedded Systems. I have skills in Autocad, Proteus, C++, C programming and i love to share these skills to other to enhance my knowledge too.
