Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

36. Figure P36.35 shows a radio-wave transmitter and a receiver
separated by a distance d and both a distance h above the
ground. The receiver can receive signals both directly from
the transmitter and indirectly from signals that reflect
from the ground. Assume the ground is level between the
transmitter and receiver and a 180* phase shift occurs upon
reflection. Determine the longest wavelengths that interfere
(a) constructively and (b) destructively.
