Electromagnetism is one of the fundamental forces in nature. It describes the interactions between electric and magnetic fields, which can be observed throughout our universe. Electromagnetic energy is responsible for many phenomena that occur in everyday life, such as electricity flowing through wires or light radiating from a lamp. The study of electromagnetism has led… Read More

The Electromagnetic Spectrum, which goes by either (EMS) or, depending on context (ES), defines the available ranges of all frequencies of Electromagnetic Radiation (EMR) or (ER). The spectrum ranges from exceptionally low frequencies, such as those used for radio waves, to high frequencies, such as gamma rays. Electromagnetic radiation can be divided into several categories… Read More

A photon is a particle of light and is the basic unit that makes up all electromagnetic radiation. photons are emitted when an atom or molecule undergoes a change in energy level, and are absorbed when they are incident on another atom or molecule and raise its energy level. The word “photon” comes from the… Read More

Electromagnetic radiation is a type of energy that travels through the air and other materials at the speed of light. It includes visible light, infrared radiation, ultraviolet rays, x-rays, and gamma rays. All matter is made up of atoms. Atoms are made up of smaller particles called protons and electrons. Protons have a positive charge… Read More
