... By: Nozomu Tokiwa Experiment Done with Alberico Bello Experiment: 19/09/08 Report Written: 3/10/08 A: Rotating Mirror Aim: To find how light reflects, and how the angle turned by reflected ray changes as angle turned by mirror changes Hypothesis: The angle of incidence and the angle of reflection will be the same. I also think that if the angle turned by mirror becomes bigger, the angle turned by reflected ray also gets bigger. Materials: -Paper -Pencil -Mirror -Ray-box -Protractor -Ruler -Power source Method: First, we got a paper, a ray-box, and a mirror. Then we drew two lines on the paper so that they crossed each other at an angle, as you can see in the diagram. The angle we used here was 20 degrees. We labeled the two lines M1 and M2, as you can see in the diagram, M1 meaning 'Mirror, first position' and M2 meaning 'Mirror, second position'. We also labeled down 'Angle turned by mirror' on where the two lines crossed,
