4. Two radio antennas separated by 300 m as shown in simultaneously broadcast identical signals at the same wavelength. A radio in a car traveling due north receives the signals. (a) If the car is at the position of the second maximum, what is the wavelength of the signals? (b) How much farther must the car travel to encounter the next maximum in reception?

Step 1
We have two radio antennas separated by 300 m, broadcasting identical signals. The car is at the position of the second maximum. We need to find the wavelength of the signals and the distance to the next maximum. Show more…

Two radio antennas separated by $300 \mathrm{~m}$, as shown $\mathrm{P} 24.7$, simultaneously transmit identical signals of the same wavelength. A radio in a car traveling due north receives the signals. (a) If the car is at the position of the second maximum, what is the wavelength of the signals? (b) How much farther must the car travel to encounter the next minimum in reception? Hint: Determine the path difference between the two signals at the two locations of the car.
Two radio antennas separated by 300 $\mathrm{m}$ as shown in Figure $\mathrm{P} 37.3$ simultancously broadcast identical signals at the same wavelength. A radio in a car traveling due north receives the signals. (a) If the car is at the position of the second maximum, what is the wavelength of the signals? (b) How much farther must the car travel to encounter the next minimum in reception? (Note: Do not use the small-angle approximation in this problem.)
