A person with a radio-wave receiver starts out equidistant from two FM radio transmitters A and B that are 11.0 m apart, each one emitting in-phase radio waves at 93.5 MHz . She then walks so that she always remains 50.0 m from transmitter B. (See (Figure 1).) Limit your solution to the cases where 50.0m≤x≤65.0m.
A) For what values of x will she find the radio signal to be maximally enhanced?
B) For what values of x will she find the radio signal to be cancelled?

A person driving at 17.m/s crosses the line connecting two radio transmitters at right angles, as shown in the figure (d1 = 390 m and d2 = 130.m). The transmitters emit identical signals in phase with each other, which the driver receives on the car radio. When the car is at point A the radio picks up a maximum net signal.

12. The waves from a radio station can reach a home receiver by two paths. One is a straight- line path from transmitter to home, a distance of 30.0 km. The second is by reflection from the ionosphere (a layer of ionized air molecules high in the atmosphere). Assume this reflection takes place at a point midway between receiver and transmitter, the wavelength broadcast by the radio station is 350 m, and no phase change occurs on reflection. Find the...

Question1. A U.S. or Canadian broadcasting licence for a (large) FM radio station stipulates a maximum broadcast power of 100 kW. At any distance from the broadcast antenna the intensity doesn’t quite follow the inverse square law that is described for spherical waves in the videos lectures, because of reflection of the signal off of the ground. But the inverse square law is not a bad approximation, so let’s use it a) Find the intensity of the radio signal from...
