If the LAW OF REFLECTION is obeyed, that is-- angle of incidence equals angle of reflection, then could it be proved geometrically that:
in spherical mirrors,
>a ray parallel to the principal axis will be reflected so that it passes or seems to pass through the focal point?
>a ray passing or seeming to pass through the focal point will be reflected parallel to the principal axis ?
how is it proved? (if you need to draw illustrations just send it to goldenageofgreece@yahoo.com, please...)
