Electromagnetic Wave Theory
Storyboard Text
- Great! Amy is now in the lead.Our next scientist is Heinreich Hertz!
- Me, me! He showed experimental evidence ofelectromagnetic waves and their link to light. The unit of frequency is also named after him!
- You're right, Lia! Now, James Clerk Maxwell!
- I know! He contributed in developing equations that showed the relationship of electricity and magnetism.
- What a close match. How about Guglielmo Marconi?
- Me! He experimented with electromagnetic waves to send messages wirelessly, developing the first apparatus for long-distance radio communication. He was inspired Heinrich Hertz's work.
- Everyone now has 2 points, and there are only 3 scientists left.Hans Christian Oersted, go!
- Aw shucks! I was about to answer.
- My turn, Oersted discovered that a magnetic needle perpendicularly aligns itself with a current-carrying wire, a definite experimental proof of the relationship between electricity and magnetism.
- Another point for Sophia. Georg Simon Ohm!
- Okay, me! He's known for his Ohm's Law, describing the mathematical relationship between electrical current, resistance and voltage.
- The last one, Alessandro Volta.
- Congratulations, Sofia! This was fun, we recalled all of them!
- Me, me! He invented the first electric battery, and proposed that an electrical current is generated by contact between different metals.
- That's right! Sophia is the winner of this game!
