There are two coherent microwave sources in the x–y plane. these sources are emitting in phase at a wavelength of =1.78 cm. one of the sources, , is located along the y ‑axis at y1, and the second source, , is located at the point x2=3.74 cm, y2=13.4 cm. assume y1> y2. if the phase difference at the origin between the two sources is =152∘, where is the first source located on the y ‑axis?

Explanation:

As we know the relation between phase difference and path difference

so we will have

now distance of two sources are

Now we have
