The discussion clarifies the concept of the angle of deviation in the context of plane mirror reflection. It establishes that the angle of deviation (D) is calculated using the formula D = 180 - 2i, where 'i' represents the angle of incidence. The relationship between the angle of incidence and the angle of reflection is emphasized, confirming that for a plane mirror, the angle of reflection (r) equals the angle of incidence (i). Thus, the angle between the reflected ray and the incident ray is expressed as 180 - D.
