Problem
Two identical plane mirrors are arranged so that a horizontal light beam traveling east strikes Mirror 1, reflects toward the south, strikes Mirror 2 located directly south of Mirror 1, and finally exits vertically upward. Mirror 1 can rotate only about a vertical axis, and Mirror 2 can rotate only about a horizontal axis. Determine the angle each mirror’s surface must make with the horizontal so the described path occurs.
