2. Gauss’s Law in Three Dimensions
1 Put Metal fork into microwave---nothing visible happens
2 Put CD into microwave.--- CD is burned
3 Put fire into microwave.---fire gets larger.
4 Put light into microwave.---to be lighter but the light is broken soon.
5 Put a soap into a microwave.--- Nothing happen
6 Put a purple metal ball into the microwave.---got burn and the fire changes color.
Summary:
In today’s class, we learn what is flux and Gauss’s Law. We know that flux is calculated by the number of electric field lines, and its go through the surface area. And we know how microwave works and how it can heat things up. We also learn what kind of material is able to absorb microwave and what kind of material is not able to absorb microwave.
