- Good morning students! Are you all ready for our science class? Let's start by presenting the assignments I gave you all!
- ELECTROMAGNETIC THEORY
- Let's start with you Matthew, you seem like you are excited to present.
- Hello everyone! I am Matthew and today I will present Heinrich Hertz who is one of the scientist who contributed in electromagnetic theory. Heinrich was a brilliant German physicist and experimentalist Hertz used a simple homemade experimental apparatus, involving an induction coil and a Leyden jar (the original capacitor) to create electromagnetic waves and a spark gap between two brass spheres to detect them. The gaps were difficult to see, and required that the he perform his investigations in a darkened room.
- In later experiments, he was able to calculate the speed of the radio waves he created, and found it to be the same as the speed of light. A great number of subsequent developments, like radio and television, not to mention Wi-Fi, were spun out of his simple demonstrations. Pretty cool right? Well my friend that is my presentation about Heinrich Hertz.
