Question

Two antennas located at points A and B are broadcasting radio waves of frequency 96 MHz. The signals start in phase with each other. The two antennas are separated by a distance d=11.2 m. An observer is located at point P on the x axis, a distance x=97 m from antenna A. The points A, P and B form a right triangle.

A) What is the phase difference between the waves arriving at P from antennas A and B? Enter your answer in radians (rad).       1.2957 rad      (correct)

B) Now observer P walks along the x axis toward antenna A. What is P's distance from A when they first observe fully constructive interference between the two waves?       20.0704 m (incorrect)

C) 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? 4   (incorrect)

Can you please help with parts B and C.
