Electromagnetic Waves
Light, microwaves, x-rays, and TV and radio transmissions are all kinds of electromagnetic waves. Different waves are made by their wavelengths. Electric fields are created by differences in voltage, the higher the voltage, the stronger will be the resultant field. Magnetic fields are created when electric current flows, the greater the current, the stronger the magnetic field. An electric field will exist even when there is no current flowing. Electromagnetic fields are found everywhere in nature, but are invisible to the human eye. There are also many human-made electromagnetic fields. An example of a human-made electromagnetic wave are X-Rays. There are many other types of waves that you can see on this website. Feel free to explore this website to the full extent.
