Radio station KSON in San Diego broadcasts at both 1240 kHz (AM) and 97.3 MHz (FM). a) Which of these signals, AM or FM, has the longer wavelength? b) How long is each

A traveling electromagnetic wave in a vacuum has an electric field amplitude of 92.9 V/m. Calculate the intensity S of this wave. Then, determine the amount of energy U that flows through area of 0.0279 m? over an interval of 18.1 s, assuming that the area is perpendicular to the direction of wave propagation. S = W/m? U = J

The call numbers for FM radio stations are given in MHz and range from 88 MHz to 108 MHz. Our college radio station is WZBT and can be found at 91.1 on your FM dial. What is the wavelength of the radio waves transmitted by WZBT?

Microwaves are produced with an intensity of 1.42 W/m² which are polarized at an angle of -84.1 degrees. What intensity in W/m2 will be measured with a receiver which only detects microwaves at an angle of 30.3 degrees? (State answer with 2 digits right of decimal. Do not include unit.)

An anstonomer on a planet orbiting the star Deneb wants to differentiate the reflected light by Earth from the light of the Sun. First, consider the area of Earths disk which reflects the Sun's intercepted light. Second, consider the surface area of a sphere with the same radius as Earths orbit around the Sun. Take the ratio of these two areas. Assume the Earths radius is 6400.0 km and is 1.3 x108 km from the Sun.

In the U.S., two different frequency ranges are allocated for over-the-air radio broadcast: the AM radio band, in the range 540-1600 kHz, and the FM radio band, in the range 88-108 MHz. (a) Find the longest and shortest wavelengths (in m) in the AM band. longest m shortest (b) Find the longest and shortest wavelength (in m) in the FM band. longest m shortest Need Help? Read It

What is the wavelength of light if its frequency is 1.4 x 104 Hz? Assume the light is traveling through a vacuum.

Compute the wavelength of the radio waves from the following stations. (a) an AM station operating at a frequency of 790 kHz m (b) an FM station with a frequency of 98.3 MHz m

Electromagnetic radiation having a 15.0 µm wavelength is classified as infrared radiation. What is its frequency (in Hz)?

(a) Approximately how long would it take a telephone signal to travel 2810 mi from coast to coast across the United States? (Telephone signals travel at about the speed of light.) b) Approximately how long would it take a radio signal to reach the International Space Station (ISS) at an orbital altitude of 350 km?
