Procedure: Convex Mirror 1. Adjust the position of the light source so the single light ray now hits the concave mirror at the point the normal line extends from the outline as in Figure 8 2. Use the ruler and pen or pencil to trace the paths of the incident and reflected light rays. Label each line "Ray 1 Incident" or "Ray 1 Reflected" similar to Figure 8 to help differentiate them. 3. Lift the mirror off the paper and then use the protractor to measure the angles of both incident and reflected rays relative to the normal line. Record both values. 4. Repeat the same procedure two more times using two different incident angles. Record all data. Figure 8: Convex Mirror Reflection Analysis 1. According to the Law of Reflection, the incident angle and the reflection angle must be the same. Discuss: How well does your experiment show this? Does it matter whether the reflective surface is flat or curved? Why? 2. What are sources of experimental uncertainty for this part of the experiment
