In 1996, a phone call was placed from the U.S. National Military Command Center to the U.S. Atlantic Command, 304 km away. The phone signal, however, traveled 120 750 km because it was transmitted via a Milstar communication satellite. The satellite uses super high-frequency electromagnetic radiation to ensure reliable communication that is secured against eavesdropping. Assume these waves are passed through a diffraction grating with 1.00 x 102 lines/m. The first-order maximum appears at an angle of 30.0. Determine the wavelength and frequency of the electromagnetic waves. In 1996, a phone call was placed from the U.S. National Military Command Center to the U.S. Atlantic Command, 304 km away.
