You place two antennas 5.00 m apart, each broadcasting a 1632.0 MHz radio signal, in phase with each other and uniformly in all directions. (Radio waves move at the speed of light.) You then study the intensity at various points the same distance from the midpoint between the antennas, a distance that is very large relative to the separation between the antennas. Measuring angles from a reference line that passes through this midpoint and is perpendicular to a line segment connecting the two antennas, you find the intensity along this reference line, i.e., at an angle ? of zero, to be 16.0 W/m2.

Part A

Including this central point, at how many angles in the range

    3. Two radio antennas are 100 m apart along a north-south line. They broadcast identical radio waves at a frequency of 30.0 MHz. Your job is to monitor the signal strength with a handheld receiver. To get to your first measuring point, you walk 800 m directly east from the northernmost antenna. If you now begin to walk north from this point, does the signal strength increase, decrease, or stay the same? Explain.

    An astronomical radio telescope consists of two antennas separated by a distance of 206 m. Both antennas are tuned to the frequency of 24 MHz. The signals from each antenna are fed into a common amplifier, but one signal first passes through a phase selector that delays its phase by a chosen amount so that the telescope can "look" in different directions. When the phase delay is zero, plane radio waves that are incident vertically on the antennas produce signals...
