- So class, that's it for Electromagnetic Waves
- For a quick recall, May I ask you who is James Clerk Maxwell?
- Ampere formulated a law of electromagnetism, often called Ampere's Law that mathematically describes the magnetic force between two currents. In addition to this he undertook many experiments from which he managed to explain some electromagnetic phenomena that had been o.He invented the astatic needle, a critical component of the modern astatis galvanometer, and was the first to demonstrate that a magnetic field is generated when two parallel wires are charged with electricity. He is generally credited as one of the first to discover electromagnetism.
- Very Good, and the last one scientist.
- HEINRICH HERTZ, a German physicist, applied Maxwell's theories to the production and reception of a radio waves. The unit of Frequency of radio wave one cycle per second is named, in honor of Heinrich Hertz. he produces RADIO WAVES and detected electromagnetic waves in his laboratory by using spark gap attached to an induction coil and a seperate spark gap on receiving antenna.
- HANS CHRISTIAN ORSTED was a Danish physicist and chemist who discovered that electric currents create magnetic fields. which was the first connection found between electricity and magnetism. Orsted's law and the orsted unit are name after him. his 1820 discovery marked the beginning of a revolution in the understanding of electroagnetism. providing the first connection between what had been thought to be two very different physical phenomena.
- Very Good!, next...
