What is an electromagnetic wave?

Question

is it a gravitional wave? a cosmic ray proton or a sound wave?

Answer 1

Electromagnetic radiation is generally described as a self-propagating wave in space with electric and magnetic components. They are forms of radiation on the elctromagnet ic spectrum!! These components oscillate at right angles to each other and to the direction of propagation, and are in phase with each other. Electromagnetic radiation is classified into types according to the frequency of the wave: these types include, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. In some technical contexts the entire range is referred to as just 'light'. [1]

EM radiation carries energy and momentum, which may be imparted when it interacts with matter.

Electromagnetic waves of much lower frequency than visible light were first predicted by Maxwell's equations and subsequently discovered by Heinrich Hertz. Maxwell derived a wave form of the electric and magnetic equations, revealing the wavelike nature of electric and magnetic fields and their symmetry. йō ŞрзĈ

According to these equations, a time-varying electric field generates a magnetic field and vice versa. Therefore, as an oscillating electric field generates an oscillating magnetic field, the magnetic field in turn generates an oscillating electric field, and so on. These oscillating fields together form an electromagnetic wave.

Answer 3

Light. That's right, light is elctromagnetic waves, which is a part of what is called the electromagnet spectrum. The spectrum includes radio waves, x-rays, ect.
