Reflection

Light can be a helpful tool and make fun stuff like FIRE! With reflection light goes the other way and can be manipulated and makes heat. With a parabola light hits the parabola and focuses on one focal point. It can reach up to over 530° and easily boil water. With a convex mirror you can spread light out with to get a larger area. With a plane its what comes in is what goes out. The light hits the mirror and bounce straight back. Light can go a many of ways due to reflection. That is the coolest part of reflection, you can control light.
