108 A source S and a detector D of radio waves are a distance d apart on level ground (Fig. 17-52). Radio waves of wavelength A reach D either along a straight path or by reflecting (bouncing) from a certain layer in the atmosphere. When the layer is at height H, the two waves reaching D are exactly in phase. If the layer grad- ually rises, the phase difference between the two waves gradually shifts, until they are exactly out of phase when the layer is at height H+ h. Express A in terms of d, h, and H.
