Radio waves are waves of high wavelength and low frequency in the electromagnetic wave spectrum. The Radio wave spectrum frequency ranges from 3 KHz to 3,000 GHz. Radio Waves are governed by International Telecommunication Union (ITU). The theory of Radio Waves was brough in by Physicist and Mathematician James Clerk Maxwell in 1865. In 1880s, Physicist Heinrich Rudolf Hertz proved…

Electromagetic Waves
Electromagnetic (EM) wave also known as Electromagnetic Radiation is a self-propagating wave energy that travels at the speed of light in the form oscillating electric and magnetic fields perpendicular to each other. Electromagnetic Wave is generated when electric particles are accelerated though matter which generates electromagnetic radiation. Electromagnetic waves can travel through vacuum. Accelerating electric charge…
Energy
Energy is defined as the ability to do work. It is measured in Joule (J) named after PhysicistJames Prescott Joule who discovered the relationship between mechanical energy and heat energy which led to “Law Of Conversation” which states that energy cannot be created nor destroyed but can be converted from one form to another. Energy…
