Question: Q1. On the graph sheet, please use Table I to plot the angle of reflection (Y) as a function of the angle of incidence (X).

Q1. On the graph sheet, please use Table I to plot the angle of reflection (Y) as a function of the angle of incidence (X). What is the relationship between them? Does your data support the law of reflection? Why?

Q2. According to the refraction data in Table II, will light bend towards the normal line or away from it when travelling from air to water? Why?

Q3. What value do you expect for the angle of reflection if the angle of incidence is 30 degrees? Explain your answer.

Q4. An incident ray of light forms an angle of incidence θ₁ = 30 degrees with the normal to the interface between air and glass. The observed angle of refraction is θ1 = 19.2 degrees. Assume that the index of refraction of air is n1 = 1. Calculate the index of refraction of glass n₂ using the law or refraction (Snell's Law in page 73). Show your work.
