Mobile phone:
Mobile phones use electromagnetic waves to transmit information. Mobile phones belong to mobile phones. They are both electromagnetic wave transmitters and electromagnetic wave receivers, so they use electromagnetic waves to transmit information.
Electromagnetic wave is an oscillating particle wave derived and emitted by electric field and magnetic field in the same direction and perpendicular to each other in space. It is an electromagnetic field that propagates in the form of fluctuation and has wave-particle duality. The electric and magnetic fields that oscillate in the same phase and are perpendicular to each other move in the form of waves in space, and their propagation direction is perpendicular to the plane formed by the electric and magnetic fields. Electromagnetic waves have a fixed speed in a vacuum, and the speed is the speed of light.
