(D The Law of Reflection has two parts. State both parts. You were asked to measure the angle of reflection when the ray was incident on either side of the normal to the surface of the mirror. What advan- lages does this provide? Physicists expend a great deal of energy in attempts to increase the accuracy with which an exact law can be proven valid. How might you test the Law of Reflection to a higher level of accuracy than in the experiment you just performed
