Experiment 1: Law of ReflectionIn this experiment, you will investigate reflection using a laser and mirror.MaterialsLaser PointerMirror SupportPlane MirrorProtractor *Sheet of Paper*You Must ProvideProcedure1. Place a sheet of paper on a flat surface like a table and lay the protractor over the sheet. 2. Hold the mirror vertically and place the bottom left corner of the mirror in the mirror clip so that the mirror stands on its own. 3. Line up the mirror along the base line of the protractor with the reflective side facing the angles. The bottom right corner of the mirror should rest on the origin of the protractor and the bottom left corner of the mirror should rest on the 0º mark. 4. Shine the laser at the mirror at incident angle 0°. Record the angle of the reflected beam in Table 1. Note: Angles are measured from the normal line which is the 90 degree angle. 5. Repeat Step 4 for all of the incident angles listed in Table 2 (next page). © 2014 eScience Labs, LLC.All Rights ReservedPost-Lab Questions1.
