As light is produced by the acceleration of charged particles & from law of electromagnetism that states that: an accelerated charge produce electromagnetic wave,light is an electromagnetic wave. Actually light is the transfer of energy from one part of electromagnetic field to other.

This article explains the different forms of energy, including stored or potential energy and kinetic energy. It also describes mechanical waves and electromagnetic waves as two important ways that energy is transported in the world around us. The article goes on to explain how electricity can be static or changing, forming electromagnetic waves wh...
Energy comes in many forms and can transform from one type to another, including stored or potential energy, kinetic energy, and electromagnetic radiation.
Mechanical waves are caused by a disturbance or vibration in matter while electromagnetic waves do not require a medium to propagate.
Scottish scientist James Clerk Maxwell developed the scientific theory of electromagnetic waves and Heinrich Hertz applied it to radio wave production and reception.
Light is made of photons that carry momentum, have no mass, travel at speed of light with both particle-like and wave-like properties; polarization measures alignment of electromagnetic field.
The terms light, electromagnetic waves, radiation all refer to same physical phenomenon described by frequency/wavelength/energy units for convenient use.
Apr 8, 2008 · Ultraviolet rays, visible light, infrared radiation, and microwaves fall at energy levels in between. Together, all of these make up one long, continuous electromagnetic spectrum of light. Its energy travels in what are usually referred to as waves.
Dec 28, 2020 · The EM wave propagates transversely to both. Visible light lies between 400 and 700 nm, but it is a tiny fraction of the EM spectrum overall. Electromagnetic radiation is formed from the intersection of a magnetic field and an electric field oriented perpendicularly to each other.
Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted c. There, depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced.
Nov 14, 2014 · The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.
