As shown in the figure, a ray of light strikes a plane mirror with some incident angle. The mirror is now rotated by an angle of ? = 19.0° about an axis through the point where N1 contacts the mirror, without altering the incident ray. The new position is shown by the line M2. (a) Determine the angle through which the reflected ray rotates if the incident angle is 40.0°. ° (b) Determine the angle through which the reflected ray rotates if the incident angle is 50.0°. °
