Answer:
Frequency is
Explanation:
Distance between source 1 from the receiver ,
Distance between source 2 from the receiver ,
Now ,
Path difference ,
We know, for constructive interference path difference should be integral multiple of wavelength .
Therefore,
It is given that n = 1,
Therefore,
Frequency can be found by ,
Hence, this is the required solution.
Remember that the total velocity of the motion is the vector sum of the velocity you would have in still water and the stream. Always place the vectors carefully to be able to come up with an accurate sum vector.
