The reflecting surfaces of two intersecting flat mirrors are at an angle 0 (0° < 0 < 90°) as shown in the figure below. For a light ray that strikes the horizontal mirror, show that the emerging ray will intersect the incident ray at an angle ß = 180° - 20. Assume that all angles are expressed in degrees and define the angles of incidence for the two reflections to be a and ô with respect to the normals. Calculate ß in terms of a and 8. B = Now calculate 0 in terms of a and 8. Combine the previous two results in order to obtain an expression for ß in terms of 0. B = 180 – 20
