Two points sources separated by 2.0 m are radiating in phase with λ=0.50 m. A detector moves in a circular path around the two sources in a plane containing them. How many maxima are detected ?
Alternate solution: At the end of vertical diameter, zeroth maxima (Δx=0) is obtained, and at the end of horizontal diameter 4th maxima (Δx=4λ) is obtained. Hence, there are three maxima in each quadrant and another four maxima at the ends of horizontal and vertical diameters. Therefore, total maxima =(3×4)+4=16. |
