We can represent this problem in the figure:
An omni-directional microwave source (waves goes in all directions) with λ = 0.86 m is placed next to a mirror as shown in the diagram below with L = 1 m.
a) There are spots of maximum intensity and minimum intensity along the line between P and the source. Find the smallest value of y ≠ 0 for which a minimum intensity is detected.
b) A detector located a large fixed distance (y >> 0) from the source is now moved clockwise along a semi-circular path centered at the source. Find how many maximum intensity spots will be observed by this detector as it moves from the positive y-axis to the negative y-axis.
