Unformatted text preview: uncertainty. 3. How will you know when the angle of incidence is at Brewster’s angle? Brewster’s angle is the one particular angle of incidence where the reflected beam is completely polarized. At this point, the refracted and reflected beams will be perpendicular. 4. Why is the laser beam directed through a cylindrical lens? The laser used is not wide enough for the purposes of the experiment. In order to increase the size of the beam, the cylindrical dispersion lens must be used to disperse the light on a plane perpendicular to the axis of the cylindrical lens. 5. What is another name for the Law of Refraction? The Law of Refraction is also referred to as Snell’s Law....
