Two monochromatic, coherent radio sources are located a distance D = 62.69 Cm apart, they emit radio waves with a wavelength of A = 12.22 cm. A detector moves along a track parallel to a line joining the two sources. The track is also D = 62.69 cm from the sources. The detector starts in line with the lower radio source, labeled x = 0 on the figure. ................................ 2::D ................................ 33:0 track Figure 1. Two monochromatic and coherent radio sources lie a distance D apart. A parallel track lies a distance D away. Part 1) When x = 0 what is the path difference between the radio waves coming from the two sources? Part 2) What is the phase difference between these two waves. Give your answer as a number between 0 and 2;: radians. Part 3) As the detector moves between x = 0 and x = D how many local maximums does it encounter
