In a certain experiment, a radio transmitter emits sinusoidal electromagnetic waves of frequency 115.0 MHz in opposite directions inside a narrow cavity with reflectors at both ends, causing a standing wave pattern to occur. Part A How far apart are the nodal planes of the magnetic field? Express your answer in meters. Part B If the standing wave pattern is determined to be in its eighth harmonic, how long is the cavity?
The radar gun of a police car emits an electromagnetic wave with a frequency of 7.5x10°Hz. The wave from the gun reflects from a speeding car and returns to the police car, where on board equipment measures its frequency to be greater than the emitted wave by 6.4 kHz. What is (1, 1,
Consider a cell phone that emits electromagnetic radiation with a frequency of 1.0 GHz and with a power of 80 W. (a) What is the electric field amplitude at a distance 1190 m away from the phone? Assume it radiates as a point source. (b) If your ear is only about 10 cm from the source of radiation, what is the electric field amplitude at your ear as you use the phone? Again assume the phone radiates as a point...
