Detailed explanation-1: -The Amplitude Modulated (AM radio) carrier frequencies are in the frequency range 535-1605 kHz. Carrier frequencies of 540 to 1600 kHz are assigned at 10 kHz intervals. The FM radio band is from 88 to 108 MHz between VHF television Channels 6 and 7.
Detailed explanation-2: -Radio Waves–The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves.
Detailed explanation-3: -In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
Detailed explanation-4: -Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
