(a) (b) (c) (d) (e) The maximum peaks of an electromagnetic wave are separated by a distance of 8 inches. From here, determine its frequency in megahertz and in gigahertz. Compute the width of the band of a commonly used frequency range between 902 to 928 MHz. Assuming a television signal occupies a 6-MHz bandwidth. If the low-frequency limit of channel 2 is 54 MHz, measure and decide the upper-frequency limit. A power amplifier with a 40 dB gain has an output power of 100 W. Herein, measure and suggest the input power. Three cascaded amplifiers have power gains of 5, 2, and 17, while the input power is 40 mW. Hence, find the output power
