Delta² said:E=cB is the relationship that holds between amplitudes, where E is the amplitude of the electric component and B that of the magnetic component. c is the speed of light.
If you want a bit more read the last 3 paragraphs of this wikipedia section http://en.wikipedia.org/wiki/Electromagnetic_wave#Derivation
sophiecentaur said:Not quite accurate, actually. The E and H fields are related by
Z0 = E/H
where Z0 is the Impedance of free space (approx 377Ω)
Alternatively
E/B = Z0/μ0
I don't think your formula can be obtained by rearranging the above / substituting quantities.

Electromagnetic waves are a form of energy that are created by the vibrations of electric and magnetic fields. They are generated by the movement of charged particles and travel through space at the speed of light.
The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. It includes a wide range of wavelengths, from long radio waves to short gamma rays.
Electromagnetic waves have many practical applications in our daily lives. They are used in communication technologies, such as radio and television, and in medical imaging, such as X-rays and MRI scans. They are also used in household appliances, such as microwaves and remote controls.
Yes, some forms of electromagnetic waves can be harmful to humans and other living organisms. For example, prolonged exposure to high levels of UV radiation can cause skin cancer, and excessive exposure to X-rays can damage cells and cause mutations.
Light is a type of electromagnetic wave that is visible to the human eye. However, the electromagnetic spectrum includes other types of waves that are not visible, such as radio waves and X-rays. All forms of light travel through space at the speed of light and have similar properties, such as wavelength and frequency.
