Natural Language Processing. There is a common notion that the average English-speaking adult knows between 20,000 and 30,000 words. Recently, a research was published about an analysis of 10 years worth of Wall Street Journal newspapers. It reported that after removing duplicates and names, less than 20,000 unique words were used.
Electromagnetic waves are made up of particles called Photons. Electromagnetic waves carries by the small particles named  Photon . Electromagnetic waves are made of photon charges, E=hf=hc/r = zQ2c/r, where Q is the photon charge= 4/3 E-18 Coulombs = 8 1/3 Electrons=(13U,1d) Quark.an electric field and a magnetic field that are orthogonal to each other and oscillating at the same frequency.s the electric and magnetic fields move back and forth, they create the same waves being emitted from them. They waves are called electromagnetic waves/radiation. There are 7 classifications of these waves. Radiowaves, microwaves, infrared, visible light, ultraviolet light, X-rays, and gamma rays.
An electromagnetic (EM) wave is not a sound wave. A sound wave is mechanical energy, and an electromagnetic wave is electromagnetic energy. The EM wave could be a radio or light wave, but in any case, it is composed of moving electric and magnetic fields. This electromagnetic wave can move through air or the vacuum of space, but sound (or any mechanical wave) must have a medium to travel through.
