Dear reader,
can any on explain me what is a electromagnetic wave?

please go easy with me

True! But it is even stronger. A magnetic field simply does not exist. Magnetic forces are seeming forces. In a weak analogy it is like the coriolis force: There is a force, but in fact something different than assumed at the first glance.Integral is correct, the distinction we make between Electric and Magnetic fields is purely man made.
by relativistic causes - see those charges contracted;

On most illustrations you see the electric wave and magnetic wave are "in sync". Aren't they really 90 degrees phase dislocated to each other?
An electromagnetic wave is a type of energy that is made up of oscillating electric and magnetic fields. These waves are created by the acceleration of charged particles and can travel through a vacuum. They are responsible for a vast range of phenomena, from radio waves and visible light to X-rays and gamma rays.
Unlike mechanical waves, such as sound waves, electromagnetic waves do not require a medium to travel through. They can travel through a vacuum, which is an empty space with no physical matter. They also differ from sound waves in that they can travel at the speed of light.
Electromagnetic waves are classified into seven categories based on their wavelengths and frequencies: radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays. These waves have varying frequencies and energies, with radio waves having the lowest frequency and energy, and gamma rays having the highest.
Electromagnetic waves have many practical applications in our daily lives. Some common examples include using radio waves for communication, microwaves for cooking, infrared waves for remote controls, visible light for vision, and X-rays for medical imaging. They are also used in technologies such as radar, satellite communication, and wireless internet.
The electromagnetic spectrum is a range of all possible electromagnetic waves, sorted by their frequencies and wavelengths. Electromagnetic waves are directly related to the electromagnetic spectrum, as they differ in frequency and wavelength, but all fall under the same category of energy. This spectrum includes all types of electromagnetic waves, from radio waves with the longest wavelengths to gamma rays with the shortest wavelengths.
