Lecture on Electromagnetic Spectrum
Subject: Physics | Topics:

Electromagnetic waves come in many wavelengths and frequencies. Each one is useful in different ways. The electromagnetic spectrum is the range of all EM frequencies. The EM spectrum is a smooth, gradual progression from the lowest frequencies to the highest (and wavelengths). Radio waves are broadcasted by a transmitter where a receiver picks up the signals and converts it to sound waves. Radio stations use different frequencies so they don’t get crossed.
