Electromagnetic Wave
Storyboard Text
- Hans Christian Ørsted - During an evening lecture in April 1820, Ørsted discovered that a magnetic needle aligns itself perpendicularly to a current-carrying wire, definite experimental evidence of the relationship between electricity and magnetism.
- André Marie Ampère - French physicist who founded and named the science of electrodynamics, now known as electromagnetism. He also formulated a law of electromagnetism, called Ampère's law, that describes the magnetic force between two electric currents.

- Michael Faraday - An English scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis.
- James Clerk Maxwell - One of the first things that Maxwell did with the equations was to calculate the speed of an electromagnetic wave and found that the speed of an electromagnetic wave was almost identical to the speed of light. Based on this discovery, he was the first to propose that light was an electromagnetic wave.
- Heinrich Hertz - A brilliant German physicist and experimentalist who demonstrated that the electromagnetic waves predicted by James Clerk Maxwell actually exist.
