Two antennas located at points A and B are broadcasting radio waves of frequency 93 MHz. The signals start in phase with each other. The two antennas are separated by a distance d = 8.5 m. An observer is located at point P on the z axis, a distance z = 91 m from antenna A. The points A, P and B form a right triangle.

Two Antennas
Two antennas located at points A and B are broadcasting radio waves of frequency 93 MHz. The signals start in phase with each other. The two antennas are separated by a distance d = 8.5 m. An observer is located at point P
on the axis, a distance x = 91 m from antenna A. The points A, P and B form a right triangle.
A
P
Phase
What is the phase difference between the waves arriving at P from antennas A and B? Enter your answer in radians (rad).
phase=
movein
X
Now observer P walks along the axis toward antenna A. What is P's distance from A when they first observe fully constructive interference between the two waves?
distance=
places
If observer P continues walking until they reach antenna A, at how many places along the x axis (including the place you found in the previous problem) will they find maxima in the radio signal due to constructive
interference?
maxima=
