I want to know in details
what is the main origin of electromagnetic waves?
and thanks a lot in advance.

If you want a straightforward introduction to Maxwell's equations that covers up to electromagnetic waves, I suggest "A Student's Guide To Maxwell's Equations" by Fleisch - this introduces vector calculus too.
The main origin of electromagnetic waves is the movement of electrically charged particles. This can occur naturally, such as in the case of lightning, or artificially, such as in the transmission of radio signals.
Electromagnetic waves are created when an electric field and a magnetic field interact with each other. This can happen when an electrically charged particle accelerates or changes direction.
There are many different types of electromagnetic waves, ranging from radio waves to gamma rays. They are categorized based on their wavelengths and frequencies, which determine their properties and uses.
The speed of electromagnetic waves is approximately 300 million meters per second, which is equivalent to the speed of light. This speed is constant and is denoted by the letter "c" in scientific equations.
Electromagnetic waves can interact with matter in various ways, depending on the properties of the material. They can be absorbed, reflected, or transmitted through materials. The interaction of electromagnetic waves with matter is the basis for many technologies, such as X-rays and microwave ovens.
