Physiological optics 5 th lecture. Dr. Mohammad Shehadeh. Reflection of Light. When light meets an interface between two media, its behaviour depends on the nature of the two media involved. Light may be absorbed by the new medium, or transmitted onward through it
Dr. Mohammad Shehadeh
(1) The incident ray, the reflected ray and the normal to the reflecting surface all lie in the same plane. (The 'normal' is a line perpendicular to the surface at the point of reflection.)
(2) Angle of incidence, i, equals the angle of reflection, r.
( direction from which light enters the eye. Light from object O appears to come from point I, the image of O. b) Object between centre of curvature C, and principal focus F.
(c) Object inside principal focus F. direction from which light enters the eye. Light from object O appears to come from point I, the image of O.
