- SCIENCE 10ELECTROMAGNETIC WAVE
- Let us have a short recall. Who are the scientists and what are their contributions?
- Yesterday we discussed about, scientists with their contributions on the discoveries of electricity and magnetism and the development of Electromagnetic wave theory.
- James Clerk Maxwell contributed in developing equations that showed the relationship of electricity and magnetism. He noticed that electrical field and magnetic field can couple together to form electromagnetic waves.
- Heinrich Hertz showed experimental evidence of electromagnetic waves and their link to light, and proved the existence of radio waves in the late 1880s.
- Michael Faraday formulated the principle behind electromagnetic induction. It is a seminal breakthrough which laid the groundwork for later researchers such as James Clerk Maxwell, and led to important inventions such as electric motors, transformers, inductors, and generators.
- Andre-Marie Ampere demonstrate the magnetic effect based on the direction of current.
- and Hans Christian Oersted showed how current carrying wire behaves like a magnet
- Impressive!
