# A report onElectromagnetic radiation, Light and Maxwell's equations                      Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye.

- Light

It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.

Known as electromagnetic radiation, these waves occur at various wavelengths to produce a spectrum of radiation from radio waves to gamma rays.

- Maxwell's equations

According to Maxwell's equations, a spatially varying electric field is always associated with a magnetic field that changes over time.

The speed calculated for electromagnetic waves, which could be predicted from experiments on charges and currents, matches the speed of light; indeed, light is one form of electromagnetic radiation (as are X-rays, radio waves, and others).

- Maxwell's equations

In 1873, he published A Treatise on Electricity and Magnetism, which contained a full mathematical description of the behavior of electric and magnetic fields, still known as Maxwell's equations.

James Clerk Maxwell's 1865 prediction that light was an electromagnetic wave – which was confirmed experimentally in 1888 by Heinrich Hertz's detection of radio waves – seemed to be the final blow to particle models of light. ## Speed of light

Universal physical constant that is important in many areas of physics.

Universal physical constant that is important in many areas of physics.            All forms of electromagnetic radiation, including visible light, travel at the speed of light.

The classical behaviour of the electromagnetic field is described by Maxwell's equations, which predict that the speed c with which electromagnetic waves (such as light) propagate in vacuum is related to the distributed capacitance and inductance of vacuum, otherwise respectively known as the electric constant ε0 and the magnetic constant μ0, by the equation ## Electromagnetism

Branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.

Branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.      The electromagnetic force is carried by electromagnetic fields composed of electric fields and magnetic fields, and it is responsible for electromagnetic radiation such as light.

Most prominently, Maxwell's equations describe how electric and magnetic fields are generated and altered by each other and by charges and currents. ## Electron

Subatomic particle whose electric charge is negative one elementary charge.

Subatomic particle whose electric charge is negative one elementary charge.                  In his 1924 dissertation Recherches sur la théorie des quanta (Research on Quantum Theory), French physicist Louis de Broglie hypothesized that all matter can be represented as a de Broglie wave in the manner of light.

These interactions are described mathematically by Maxwell's equations.

According to classical physics, these massive stellar objects exert a gravitational attraction that is strong enough to prevent anything, even electromagnetic radiation, from escaping past the Schwarzschild radius. ## Electromagnetic spectrum
