A ray of light strikes a mirror and is reflected so that the angle between the incident and the reflected beam is 30^o. (a) If the mirror is rotated to increase the angle of incidence by 1^o, what will be the new angle between the incident and the reflected beam? (b) If, instead, the mirror is moved to decrease the angle of incidence by 1^o, what will be the new angle between the incident and the reflected beam?
