Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

In this lab‚ the ideal gas law helps determine and evaluate the molar mass of gases and volatile liquids. The ideal gas law compares four properties of a gas which include pressure‚ volume‚ moles‚ and temperature. During this experiment‚ the moles would be unknown‚ in effect the student must use a substance mass divided by its molar mass. With this‚ the ideal gas law can be arranged in an equation fit for helping the student determine the molar mass of a gas. Purpose: The purpose of the lab is to
