Refraction & Reflection
When light encounters a different medium than the one it is already in, it bends! This phenomenon in physics is known as refraction.
Total internal reflection is a phenomenon which occurs when a propagating wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface.
