OUTCOME
By the end of this lesson you will be able to describe and explain the total internal reflection and how it relates to Snell's law and refractive index
Total Internal reflection occurs when light moves from a more dense medium to a less dense medium. It can be predicted using Snell's law
LEARNING TASKS
