2-8 Refraction and polarization of light 5. Experiment Results A. Linearity of light 1. The light beam does go straight when we tested on the angle board. 2. As the source of light beam was getting farther away from the slit‚ the beam becomes narrower and shorter in addition to fading. This is because light particles escape more when they travel to go through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface
