What is total internal reflection?
When a wave bends so much at the interface between media that it reflects back into the original medium instead of refracting out into the new medium
An electromagnetic wave with slightly more energy and shorter wavelength than ultraviolet light; waves that are commonly used for imagining structures inside the body
The collection of closely spaced light reflections off many surfaces
The changing of a wave’s speed as it travels into a medium
