Electromagnetic Spectrum Radio Waves
Electromagnetic spectrum is the classification of these waves according to their frequency.

Electromagnetic spectrum radio waves. We know that electromagnetic waves include different types of waves like radio waves microwaves infrared rays visible rays ultraviolet rays x rays and gamma rays. They range from the length of a football to larger than our planet. Radio waves gamma rays visible light and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic waves in electromagnetic spectrum.
Like all other electromagnetic waves radio waves travel at the speed of light. Different parts of the electromagnetic spectrum interact with matter in different ways and have different uses. Electromagnetic spectrum the entire distribution of electromagnetic radiation according to frequency or wavelengthalthough all electromagnetic waves travel at the speed of light in a vacuum they do so at a wide range of frequencies wavelengths and photon energies. Radio waves are a type of electromagnetic em radiation with wavelengths in the electromagnetic spectrum longer than infrared light.
Electromagnetic radiation can be described in terms of a stream of mass less particles called photons each traveling in a wave like pattern at the speed of light. Radio waves are divided into. Heinrich hertz proved the existence of radio waves in the late 1880s. Radio waves are the lowest frequencies in the electromagnetic spectrum and are used mainly for communications.
Each photon contains a certain amount of energy. Radio waves have the longest wavelengths in the electromagnetic spectrum. The entire range electromagnetic spectrum is given by radio waves microwaves infrared radiation visible light ultra violet radiation x rays gamma rays and cosmic rays in the increasing order of frequency and decreasing order of wavelength. The electromagnetic spectrum comprises the span of all electromagnetic radiation and consists of many subranges commonly.
Electromagnetic waves travel at 300 million metres per second ms through a vacuum. They have have frequencies from 300 ghz to as low as 3 khz and corresponding wavelengths from 1 millimeter to 100 kilometers.
