There are two coherent microwave sources in the x-y plane. These sources are emitting in phase at a wavelength of ? = 1.00 cm. One of the sources, S1, is located along the y axis at y1, while the second source, S2, is located at the point x2 = 4.90 cm, y2 = 15.1 cm. If the phase difference at the origin between the two sources is ? = 113°, where is the first source located on the y axis (assume y1 > y2)?
