The light ray in the subsequent figure emanates from a point on one wall of a room and is incident on a plane mirror that lies flat on the opposite wall. The reflected ray strikes the left-hand wall at point A, which is a distance h =1.1 m below the light source, and d = 2.4 m from the mirror. What is the angle of incidence θi?
