In one of my old physics textbooks, there was a story about a scientist who was demonstrating electricity when it was a pretty new discovery. He had some sort of electrical device that he was showing and at one point he had it near a magnet. It didn't work as expected because of the magnet. The...
Ah! Google seems to know what I'm looking for when I search for diffraction. We did diffraction in the previous physics course, but it was just about what happens when you shine a light from one material through to the other. I probably should have made the connection, but I didn't. Thank...
In a general physics class, one of the things we are studying is light waves. Optics is my biggest struggle within physics anyway, and now my book is explaining what happens when a laser is pointed through a barrier with holes on it. It includes some trigonometric formulas for...I don't even...
