Summary
Electromagnetic Radiation is basicly about the transmission of energy in the form of waves that extend from the logest radio waves to the shortest gamma rays. Water waves may be used to represent how light moves through space. But, light waves are very different than water waves in many ways. That's because in water waves, particles vibrate up and down as the wave passes through the water. In a light wave however, the electrical and magnetic fields vibrate. That is the reason why light waves are classified as electromagnetic radiation.
