##### 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 $lambda$ 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 $mathrm{D}$ are exactly in phase. If the layer gradually rises, the phase difference between the two waves gradually shifts, until they are exactly out of phase when the layer is at height $H+h$. Exp
