Electromagnetic waves are a type of energy that is created by the movement of electrically charged particles. They are invisible to the human eye, but can be detected by special instruments. They are also known as EM waves or radiation.
Electromagnetic waves are a broad spectrum of energy that includes light. Light is a specific type of electromagnetic wave that is visible to the human eye. Other types of electromagnetic waves include radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays.
Electromagnetic waves do not require a medium to travel through, unlike sound waves which need a material medium. They can travel through a vacuum, such as outer space, at the speed of light.
Electromagnetic waves have a wide range of applications in various fields. Some examples include communication (radio waves), cooking (microwaves), medical imaging (X-rays), and energy production (solar panels).
Electromagnetic waves are produced when an electrically charged particle, such as an electron, is accelerated or decelerated. This creates a disturbance in the electromagnetic field, resulting in the emission of electromagnetic waves.
