Figure 1. Set up the mirror and laser as depicted in figure one. Set a base angle so that all measurements can be taken from that point. Rotate the mirror and record the angle of deflection, see table 1.1. Plot the angle of the deflected laser beam as a function of the mirror angle, see figure 1.a for the plot. Measurement Mirror angle Deflection angle 1 45° 92° 2 55° 112° 3 65° 132° 4 75° 152° 5 85° 172° 6 95° 197° Table 1.1 X Y 50 60 70 80 90 100 110 120 100 110 120 130 140 150 160 170 180 190 200 210 220 230 240 250 Deflected Angle Figure 1.a Mirror Angle any mirror angle above 95 degrees is a prediction and is denoted by x’s.

Figure 2 In figure two the mirrors are parallel to each other and should have no angular deflection. To prove this, the laser beam was allowed to reflect upon the mirror configuration and the path of the laser beam was recorded on the beam field. The mirrors were then rotated to the maximum angle that would still allow the laser beam to pass.
