About 150 years ago, James Clerk Maxwell, an English scientist, developed a scientific theory to explain the behaviour of electricity and magnetism, and discovered mathematical equations that he found predicted the existence of the new phenomenon of electromagnetic waves, which included light waves, that travel at a finite speed that he predicted.
He noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves. Neither an electrical field (like the static which forms when you rub your feet on a carpet), nor a magnetic field (like the one that holds a magnet onto your refrigerator) will go anywhere by themselves. But, Maxwell discovered that a CHANGING magnetic field will induce a CHANGING electric field and vice-versa.
James Clerk Maxwell
An electromagnetic wave exists when the changing magnetic field causes a changing electric field, which then causes another changing magnetic field, and so on forever. Unlike a STATIC field, a wave cannot exist unless it is moving. Once created, an electromagnetic wave will continue on forever unless it is absorbed by matter. Heinrich Hertz, a German physicist, applied Maxwell's theories to the production and reception of radio waves. The unit of frequency of a radio wave -- one cycle per second -- is named the hertz, in honor of Heinrich Hertz.
Hertz proved the existence of radio waves in the late 1880s. He used two rods to serve as a receiver and a spark gap as the receiving antennae. Where the waves were picked up, a spark would jump. Hertz showed in his experiments that these signals possessed all of the properties of electromagnetic waves.
Heinrich Hertz
With this oscillator, Hertz solved two problems. First, timing Maxwell's waves. He had demonstrated, in the concrete, what Maxwell had only theorized - that the velocity of radio waves was equal to the velocity of light! (This proved that radio waves were a form of light!) Second, Hertz found out how to make the electric and magnetic fields detach themselves from wires and go free as Maxwell's waves.

British physicist James Clerk Maxwell was the first to demonstrate that light consists of electromagnetic waves. His theory of electromagnetics was published in the 1860s.
He is famous for his theory of electromagnetics, described in his "Treatise on electricity and magnetism", published in 1873, which is the basis for electrical physics, electrical and electronic engineering and therefore much of what makes modern life what is it.
That it is a part of the electromagnetic spectrum
Yes, more or less. James Clerk Maxwell predicted that an electromagnetic wave would propagate at the speed of light. Therefore, he also suspected that light was an electromagnetic wave. This was confirmed later.Yes, more or less. James Clerk Maxwell predicted that an electromagnetic wave would propagate at the speed of light.

James Clerk Maxwell made significant contributions to the field of physics, particularly in the study of electromagnetism. He formulated a set of equations, known as Maxwell's equations, which unified the laws of electricity and magnetism. This work laid the foundation for the development of modern electrical and communication technologies, such as radio and television. Maxwell's discoveries also paved the way for Albert Einstein's theory of relativity.
Electromagnetic waves were predicted mathematically by James Clerk Maxwell and later discovered by Heinrich Hertz.
Electromagnetic theory, a branch of physics involving electricity and magnetism. Maxwell produced a mathematical theory linked the two physical effects in a unified theory.
James Clerk Maxwell came up with the Theory of Electromagnetic Radiation.He stated that, "When electrically charged particle moves under acceleration, alternating electrical and magnetic fields are produced and transmitted in the forms of waves called electromagnetic waves or electromagnetic radiation."This is the Theory of Electromagnetic Radiation.
Hertz proved the existence of electromagnetic waves with James Maxwell's electromagnetic theory of light. He proved the theory by creating instruments to transmit and receive radio pulses using procedures that ruled out all wireless phenomena.

James Clerk Maxwell first theoretically predicted the existence of electromagnetic waves, however David Edward Hughes is partially credited as he made the first successful radio transmission. Heinrich Hertz is the man who actually proved Maxwell's theory of the existence of electromagnetic waves.
