ANSWER:
Step 1 of 2
Here we need to find the new angle between the incident and reflected beams. Initially when a laser beam is reflected by a plane mirror, the angle between the incident and reflected beam is . In the final case, the mirror is rotated in such a way that the angle of incidence increases by , where is the initial angle of incidence.
