The students take the following set of measurements: Angle of incidence of the light in the air above the plastic block: 30° Angle of refraction of the beam as it enters the plastic from the air: 45° Angle of refraction of the beam as it enters the plastic from the gas: 45° The three measurements are shared with a second lab group.
