1. Find the angle of refraction if a ray of light traveling through water is incident on glass at an angle of 23°. The index of refraction of water is 1.33 and the index of refraction of glass is 1.52.
2. Find the angle of refraction if a ray of light traveling through glass is incident on air at an angle of 19.99°. The index of refraction of glass is 1.52 and the index of refraction of air is 1.00.
3. Use your results from the previous two questions and make a claim about the general behavior of refracted light when it passes from a higher index of refraction into a lower index and when it passes from a lower index into a higher one.
Bonus Question: Instead of using the answers to questions 1 & 2, use Snell's Law, without any specific numbers (i.e purely algebraically) to answer question 3.
