A radio broadcast antenna is 36.00 km from your house Suppose an airplane is flying 2.230 km above me line connecting the broadcast antenna and your radio and that waves reflected from the airplane travel 88.00 wavelengths farther than waves that travel directly from the antenna to your house, (a) Do you observe constructive or destructive interference between the direct and reflected waves? ( Hint Does a phase change occur when the waves are reflected?) (b) The situation just described occurs when the plane is above a point on the ground that is two thirds of the way from the antenna to your house. What is the wavelength of the radio waves?

I can analyze electromagnetic waves in terms of color.
An AM radio station broadcasts around 1600 kHz while an FM radio stationbroadcasts at 105.3 MHz. Find the wavelength of each broadcast and identify whichstation broadcasts with higher energy waves.
Two Antennas
Two antennas located at points A and B are broadcasting radio waves of frequency 102.0 MHz. The signals start in phase with each other. The two antennas are separated by a distance d = 11.8 m. An observer is located at point P on the x axis, a distance x = 95.0 m from antenna A. The points A, P, and B form a right triangle.
What is the phase difference between the waves arriving at P from antennas A and B? Enter your answer in radians.
Anna Litical is listening to FIZX - 1040 kiloHertz on the dial. FIZX broadcasts from a location of about 78 kilometers from her home. Regrettably for Anna, the presence of a long mountain range with steep cliffs reflects the signal to her home and causes destructive interference. The mountain cliffs are located directly behind her home relative to a line drawn from the broadcasting station to her home. What is the minimum distance that the mountain cliffs are located behind her home? (Assume that the reflected wave does not undergo a phase change upon reflection off the mountain.)
