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. (a) What is the longest possible wavelength of the radio waves? 260 m (b) How long after the car...

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.

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...

Two radio antennas separated by d = 290 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 = 1140 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. d F------ (a) If the car is at the position of the second maximum after that at point o...

Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...
