Optics and Optical Illusions

[ThePhantom]

In physics, we are learning about how light, waves, and optics work. It's interesting how concave and convex mirrors operate, how the light reacts to everything. With concave and especially convex mirrors, you will see images that aren't real, because your brain traces a path of light and thinks that it should originate from somewhere when it really doesn't. The picture below is a good example, using a concave mirror. If a real object is between the focal point and the mirror, a virtual image appears behind the mirror, because your brain thinks the light should form an image there. Interesting, hmm?

yeah, we learned about this last year in physics. I think this was my favorite part of the year in that class. I actually understood it and its pretty trippy
