Reflection and Refraction
Purpose The purpose of the reflection and refraction lab was to get experimental values for the refractive index of certain materials, and compare them to known values. Additionally, we did an experiment to demonstrate the law of reflection. ... The law of reflection. ... By sighting on that pin, we also pinned the location of the reflection of the pin in the three mirrors. ... The index of refraction for glass. We had the benefit of a setup that already included the angles, so all we had to do was measure the angle of incidence and place a pin at the location of the angle of refraction.
