Journey of Electromagnetic Wave Decryption

Electromagnetic waves are wave phenomena generated by alternating changes in electric and magnetic fields. When charged particles move, an electric field is generated, and the changing electric field generates a magnetic field, which in turn generates an electric field. This mutual excitation process continues to form electromagnetic waves. In 1864, Maxwell predicted the existence of electromagnetic waves. In 1887, Hertz proved the existence of electromagnetic waves through experiments.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Electromagnetic waves are oscillating particle waves emitted in space by electric and magnetic fields that oscillate in phase and are perpendicular to each other. They are electromagnetic fields that propagate in the form of waves and have wave particle duality. Their particle form is called photons, and the relationship between electromagnetic waves and photons is not black or white, but rather two aspects of their properties that are reflected according to different practical studies. The electric and magnetic fields, which oscillate in phase and are perpendicular to each other, move in the form of waves in space, with their propagation direction perpendicular to the plane formed by the electric and magnetic fields. Electromagnetic waves have a fixed velocity in vacuum, which is the speed of light. See Maxwell's equations. The electric field direction, magnetic field direction, and propagation direction accompanying electromagnetic waves are perpendicular to each other, therefore electromagnetic waves are transverse waves. Electromagnetic waves are actually divided into radio waves and magnetic waves, which are a general term for both. However, due to the fact that electric and magnetic fields always appear, disappear, and convert into each other at the same time, they are usually referred to as electromagnetic waves together.
