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 α = 16.0° 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 50.0⁰.
