Optical phenomena

Optical phenomena are things that we can see with our eyes. They can be caused by light interacting with matter, like the sun reflecting off of water, making a rainbow. They can also be caused by light passing through a material, like when light passes through a prism and splits into different colors. Optical phenomena can also be caused by light bouncing off a surface, like when light is reflected off a mirror and onto a wall.
