My LHS class on Tuesday

My class on Tuesday was really fun. It was about Light and Lasers. First our Teacher gave us devices that allowed us to see the spectrum of light bulbs. We also learned that lasers actually have a spectrum of just 1 color. We also used learned that the angle of a mirror when you shoot a laser at it, the laser will exit on the other side at the same angle. We also used lasers to make different shapes, like a star. Then, we used a laser and shine it through a twisted glass tube, where it entered the opposite side after bouncing around inside the tube. I thought that class was really cool.
