How EM waves form
An electric charge is surrounded by an electric field. If the electric charge moves up and down, the field also moves up and down.
A changing electric field produces a magnetic field and vice versa.
The vibration of the charge starts a wave of vibrating electric and magnetic field that moves in all directions.

Properties of EM wave
Wavelength is the distance between one point to the nearest point of a wave.
Frequency is the number of wavelength that pass by a point in a certain period of time, such as second.

Properties of EM wave
As wavelength increase (longer), frequency decreases. As wavelength decreases (shorter), frequency increases.
All EM waves carry energy. The higher the frequency, the higher the energy an EM wave carry.
