Radio communication began to be used commercially around 1900. Italian inventor Guglielmo Marconi developed the first practical radio transmitters and receivers around 1894–1895. Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays - all of which are imperceptible to human eyes. The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum. Radio waves are created by the acceleration of electrons in a radio antenna, and light waves are created by the oscillations of the electrons within atoms. What is the main difference between a radio wave and light wave?īoth radio waves and light are electromagnetic waves their main difference is their frequency. The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. All it does is, just pass through, if the object it hits, allows it to pass through or it gets reflected back. You’ll get hit by way more visible light waves than radio waves each second because visible light is higher energy, and higher energy radiation has a higher frequency. Why are we getting hit by way more visible light waves than radio waves?Įnergy, wavelength and frequency Frequency is just how often something happens. Light waves with shorter wavelengths (and higher frequencies) also have more energy, so types of light like gamma rays, X-rays, and ultraviolet light are more energetic than visible light, and infrared, microwaves, and radio waves are less energetic than the light in the visible spectrum. Infrared has still more, followed by visible, ultraviolet, X-rays and gamma rays. Microwaves have a little more energy than radio waves. Radio waves have photons with the lowest energies.
