8.3: Dispersion in Optical Fiber
Light may follow a variety of paths through a fiber optic cable. Each of the paths has a different length, leading to a phenomenon known as dispersion. Dispersion distorts signals and limits

APPLIED PHYSICS UNIT
Total Internal Reflection (TIR) When light travels from a denser medium of refractive index to a rarer medium of refractive index, it bends away from the normal (as shown in fig. a), such that the angle of

The law of reflection tells us how exactly each ray of light moves when it bounces off of a surface. Due to the principle of least time, and because the speed of light stays constant in a single medium, the path
