PHYS1C Chapter 26 Notes: Image Formation by Mirrors and Lenses 26.1 Images Formed by Flat Mirrors Consider a point source of light placed at O, a distance p (object distance) from the mirror o Light rays leave source and are reflected from the mirror o When reflected, rays diverge o I is the image of the object at O, as the reflected rays converge to this point o Images are either located either at a point from which rays of light actually diverge or where the rays appear to be diverging o q is called the image distance Real vs. virtual images o Real image: formed when light rays pass through and diverge from the image point o Virtual image: formed when the light rays do not pass through the image point but only appear to diverge from that point o The image of an object seen in a flat mirror is always virtual o Real images can be displayed on a screen while virtual images cannot Geometric model of flat mirror reflections o lateral magnification M: o image is upright since the image arrow points in the same direction as the object arrow (positive value) o produces apparent leftright reversal, where your right hand in a mirror looks like your left hand, but not actually a leftright reversal; actually, a frontback reversal caused by light rays going forward toward the mirror and reflecting from it 26.2 Images Formed by Spherical Mirrors concave mirrors: light is reflected from the inner concave surface o image point is located where the reflected rays of an object converge. The rays continue to diverge after going through I o since the light rays actually pass through the image point, the image is a real image o paraxial rays: rays that diverge from an object and always reflect through the image point. Need to be small angles large angles converge at different points on the principal axis, producing a blurred image o can calculate the image distance q if you know the object distance p and radius R these distances are measured at point V
