Two radio antennas are separated by 2.00 m . Both broadcast identical 750 MHz waves. If you walk around the antennas in a circle of radius 20.0 m , how many maxima will you detect?
Interference waves of sound
1. Two loudspeakers 6.0 m apart are playing the same frequency. If you stand 10.0 m in front of the plane of the speakers, centered between them, you hear a sound ofmaximum intensity. As you walk parallel to the plane of the speakers, staying 10.0 in front of them, you first hear a minimum of sound intensity when you are directlyin front of one of the speakers. What is the frequency of the sound? Assume a sound speed of 340...

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...

Two radio antennas separated by d = 294 m as shown in the figure below simultaneously broadcast identical signals at the same wavelength. A car travels due north along a straight line at position x = 1090 m from the center point between the antennas, and its radio receives the signals. Note: Do not use the small-angle approximation in this problem. (a) If the car is at the position of the second maximum after that at point O when it...
