Questions and Answers
Electromagnetic Waves are disturbance in a field that carries energy and does not require a medium to travel. It differ in terms of wavelength, frequency and energy. Wavelength is the distance measured from one crest of a wave to the next crest or from one through to the second through, while, frequency is the number of cycles a wave completes in one second and is expressed in Hertz, and lastly, energy is carried by/ possessed by the photons. Photons are the bundles of wave energy. Types of Electromagnetic Waves Radio Waves have the longest wavelength in the electromagnetic spectrum. They are produced by making electrons vibrate in the antenna. They are used to transmit sound and pictures information over long distance. They are used mostly in Radio and Television Communication. Figure 1. A radio Microwaves can penetrate the atmosphere of the earth. Their signals are transferred by an antenna to a satellite which amplifies and re-transmits the signal to an antennae in other parts if the world.
