A radio station broadcasts its radio waves with a power of 50,000 W. What would be the intensity of this signal if it is received on a planet orbiting Proxima Centuri, the closest star to our Sun, at 4.243 ly away?
During the Cold War, American submarines operated as "lone wolves" at extreme ocean depths for many months at a time. Ordinary radio signals are greatly attenuated at such depths, making communication with the submarines difficult. One way suggested to communicate with the submarines was a program the Navy called Seafarer that used extremely low frequency waves. If the Seafarer transmitter broadcast at 82 Hz, what would the transmitter's quarter wavelength antenna have to be in order to receive the signal? km
Your favorite radio program broadcasts 96.3 MHz. What is the wavelength corresponding to this broadcast? Theoretically, the antenna of your radio is half of the wavelength of the radio waves. How long should the antenna be for this frequency?
A quarter-wave monopole radio antenna (also called a Marconi antenna) consists of a long conductor of one quarter the length of the transmitted wavelength. The lower end of the antenna is connected to a conducting ground plane (often simply the Earth) which reflects the transmitted signal, creating an effective antenna length of a half wavelength. (a) What must be the height of the antenna (in m) for a radio station broadcasting at 569 kHz? (b) What must be the height of the antenna (in m) for radio stations broadcasting at 1,750 kHz?

A radio station utilizes frequencies between commercial AM and FM. What is the frequency (in megahertz) of a 11.23 m wavelength channel?
Radio waves and microwaves are used in therapy to provide “deep heating” of tissue because the waves penetrate beneath the surface of the body and deposit energy. We define the penetration depth as the depth at which the wave intensity has decreased to 37% of its value at the surface. The penetration depth is 15 cm for 27 MHz radio waves. For radio frequencies such as this, the penetration depth is proportional to √λ, the square root of the wavelength. What is the wavelength of 27 MHz radio waves?A. 11 m B. 9.0 m C. 0.011 m D. 0.009 m
