OPTICS LAB 

The purpose of this lab is for you to gain further understanding of refraction. Towards that end, please work with your colleagues to design a lab using refraction. Some examples that came up in our brainstorming last week are:
To do these (and related) investigations, you'll need to measure the angle of incidence and the angle of refraction. You can do this using our pencil method (if you recollect that the angles are measured somewhat differently than we might expect) or use a laser pointer. The math that you need to assist you is: NOTE that the subscript 1 is the incident angle and the subscript 2 is the angle of refraction
n_{1}sin Θ_{1} = n_{2}sinΘ_{2}
v_{1}/v_{2} = n_{2}/n_{1}
sin Θ_{2}/sinΘ_{1} = v_{2}/v_{1}
