Electromagnetic radiation or electromagnetic spectrum


Electromagnetic radiation, or electromagnetic radiation or electromagnetic waves, is the amount of energy emitted in an electromagnetic process. Visible light is a form of electromagnetic radiation. Other well-known examples include radio waves; Infrared and X-rays. According to the traditional definition, electromagnetic radiation consists of the same vibrations, the electric field, and the magnetic field.

According to classical physics, electromagnetic radiation involves electromagnetic waves. These waves have parallel oscillating electric fields and magnetic fields that move at the speed of light in a vacuum. The oscillations of the two fields are perpendicular to each other and perpendicular to the direction of the wave. Therefore, they are vertical waves. Electromagnetic waves can be classified according to their frequency or wavelength. These include radio waves; Microwave Infrared Visible light; Ultraviolet light X-rays and gamma rays.

When electromagnetic particles travel at high speeds, they emit electromagnetic waves. Electromagnetic waves emit energy from a source. It carries the momentum and the angular momentum. The quantum of an electromagnetic wave is called a photon and its mass is zero. However, there is an effect of gravity. Electromagnetic waves radiate without the influence of their source. This is because they move at the speed of light and immediately exceed the potential distance of the source. Therefore, electromagnetic radiation is often referred to as the far-field.
