Electromagnetic waves were first postulated by James Clerk Maxwell and subsequently confirmed by Heinrich Hertz. Maxwell derived a wave form of the electric and magnetic equations, revealing the wave-like nature of electric and magnetic fields, and their symmetry. Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave. According to Maxwell's 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. A quantum theory of the interaction between electromagnetic radiation and matter such as electrons is described by the theory of quantum electrodynamics.
The most common type of wave is the transverse wave, where the oscillations of the wave are perpendicular to the direction of energy transfer. Sound waves, electromagnetic waves, and ocean waves are examples of transverse waves.
A transverse wave is a type of wave where the disturbance moves perpendicular to the direction of energy transfer. This means that the energy travels in the same direction as it was transferred. Examples of transverse waves include light waves and electromagnetic waves.
When it was determined that light exhibits all of the properties of wave motion, including refraction, reflection, diffraction, and dispersion, and that its speed is exactly determined by the electrical characteristics of the medium through which it propagates, just like radio, heat, ultraviolet radiation, X-rays, and gamma rays, and as predicted by the wave equation that Maxwell derived from the properties of electricity and magnetism, it then began to dawn on cutting-edge researchers that light is also an electromagnetic wave. In short, the answer to the question "why" is: Because it IS one.
An electromagnetic wave, such as light or radio waves, can travel through empty space because they do not require a medium to propagate. This is due to their unique properties of electric and magnetic fields oscillating in tandem at right angles to each other.
Radio waves are amongst the shortest. Gamma and X rays are shorter. The long wave lengths are at the other end of the electromagnetic spectrum. These are called 'infra red,
Light is said to be of dual nature so it has particle nature as well as wave nature but there is a difference in waves and electromagnetic waves. so ,as for your question "Is light a electromagnetic wave" the answer is "no"More precisely, if visible is not an electromagnetic wave, the NO part of the electromagnetic spectrum could be considered to be an electromagnetic wave. By any definition of the term, the answer is 'Yes'
Light is an example of a electromagnetic wave.
Mexican Wave? A non-electromagnetic wave.
A mechanical wave is not an electromagnetic wave.
An electromagnetic wave.
