Today we worked on reflection using mirrors, prisms, and lasers. Yes, we are really doing work with lasers. We took the time to reflect the laser off of a mirror to see how the angle of incidence and the angle of reflection are equal to each other when they are bisected by the normal. We then took the time to use a prism and laser to see how light bends when it is slowed down as the light wave travels through a denser medium.
Here is a video to explain what we are doing.
