When light hits a smooth surface: Angle of incidence = Angle of reflection (both measured from the normal). Incident ray, reflected ray and normal all lie in the same plane. Regular reflection: smooth mirror โ clear image. Diffuse reflection: rough surface โ scattered light, no clear image but whole surface visible. Plane mirror: image is virtual, erect, same size, laterally inverted, at same distance behind mirror.
