DIGITAL COMICS STRIP ABOUT THE HISTORY OF THE ELECTROMAGNETIC SPECTRUM.
Storyboard Text
- An English scientist named James Clerk Maxwell devised a scientific theory to describe electromagnetic waves over 150 years ago. Electrical and magnetic fields can combine together to generate electromagnetic waves, he discovered. In the late 1880s, Hertz demonstrated the existence of radio waves.
- Who are Heinrich Hertz and James Clerk Maxwell?
- Heinrich Hertz was a talented German physicist and experimenter who proved that James Clerk Maxwell's electromagnetic waves exist. The first field theory in physics was based on Maxwell's equations, which combined the fields of electricity and magnetism.
- Give me the names of a scientist who made a contribution to the EM theory.
- Michael Faraday, Luigi Galvani, Alessandro Volta, André-Marie Ampère and Georg Simon Ohm
- Michael Faraday FRS was an English scientist who made significant contributions to the fields of electrochemistry and electromagnetism. The principles underpinning electromagnetic induction, diamagnetism, and electrolysis were among his most important discoveries.
- Luigi Galvani discovered animal electricity and was an Italian physician, scientist, biologist, and philosopher. Bioelectromagnetics is credited to him as a forerunner. He and his wife Lucia found in 1780 that when an electrical spark contacted the muscles of dead frogs' legs, they twitched.
- What contributions did the five scientists make to the field of electromagnetic wave theory?
- Alessandro Giuseppe Antonio Anastasio Volta was an Italian physicist, chemist, and electrical and mechanical pioneer who is credited with inventing the electric battery and discovering methane. In 1774, Volwas appointed professor of physics at the Royal School of Como. His fascination in electricity prompted him to improve the electrophorus, a device for generating static electricity, in 1775. In 1776, he discovered and isolated methane gas. He was appointed to the chair of physics at the University of Pavia three years later.
- Georg Simon Ohm was a German physicist who is best known for his "Ohm's Law," which asserts that current flow in a conductor is directly proportional to the potential difference (voltage) and inversely proportional to resistance. Ohm discovered that the potential difference (voltage) applied across a conductor and the resulting electric current have a direct relation using equipment he invented. Ohm's law is the name of this relationship, and the ohm is the standard unit of electrical resistance.
- André-Marie Ampère was a French physicist and mathematician who was one of the creators of classical electromagnetism, or "electrodynamics," as he called it. He was the first to demonstrate that a magnetic field is formed when two parallel wires are charged with electricity, and he devised the astatic needle, a fundamental component of the contemporary astatis galvanometer. He is widely regarded as one of the pioneers of electromagnetic research.
