Reflections, Regractions and Lenses Objective: To examine and understand the effect of different media and how they produce discontinuities in direction through reflection and refraction. Procedure: Part I 1) Position the light source on the left end of the bench 2) Place the angular translator 25cm from the end of the light source. 3) Adjust the spinning table of the translator so that the two main lines are perpendicular and parallel to the bench. 4) Attach a aperture mask on a standard component carrier and place it between the translator and light source. Make sure the mask is y cm from the center of the translator. y is equal to the distance from the center of the translator to the analyzer holder on the spinning arm. 5) Attach a viewing screen on a special component carrier and place it on the spinning translator table. The front side of the screen should match up with the central line on the table. 6) Adjust the aperture mask's position so that its image is on the viewing screen entirely. 7) Center the image horizontally. Then turn the screen 90 degrees to center is vertically. 8) Move the viewing screen to the analyzer holder on the spinning arm, and replace it on the anglular plate with a flat surface mirror. 9) Record values of the incident and reflected angles for three different settings of incident angle.
