PHY101 Lab 12
Date: July 23rd, 2012
The purpose of this laboratory activity is to develop a set of experimental procedures that answer questions regarding Snell's Law and the index of refraction. Ultimately, the experimental procedures you develop will allow the index of refraction to be found for water and cooking oil.
1. Explain how to experimentally determine the index of refraction of two substances. 2. Develop a set of experimental procedures to find the index of refraction for water and cooking oil. 3. Calculate the index of refraction using Snell's Law. 4. Explain critical angle and total internal reflection.

In our daily life, refraction always happens and applied. When a fisherman is catching fish, the actual position of the fish is deeper than you see, because the light of the fish refracted from the water to air, and create a illusion that the position is very shallow. Moreover, everyday when people see the sun set, the actual position of sun is already totally below
