What are radiowaves and how they are formed?

Answer 1

Radio waves Radio waves are electromagnetic waves occurring on the radio frequency portion of theelectromagnetic spectrum.

Discovery and utilization

Radio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations, that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertzdemonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory. Many inventions followed, making practical the use of radio waves to transfer information through space. Nikola Tesla and Guglielmo Marconi are credited with inventing systems to allow radio waves to be used for communication.
