Below her knee If the light doesn’t get to your eye then you can’t see it You will also get images from curved mirrors: You will also get images from curved mirrors: Concave: Consider the case where the shape of the mirror is such that light rays parallel Concave: to the axis of the mirror are all “focused” to a common spot a distance f in front of the mirror: These mirrors are often sections of spheres (assumed in this class). For such “spherical” mirrors, we assume all angles are small even though we draw them big to make it easy to see… f Aside: For a spherical mirror, R = 2f R = 2f R 2f 2f center of sphere sometimes labeled “C” f Recipe for finding image: 1) Draw ray parallel to axis 2) Draw ray through focus object object 2f reflection goes through focus reflection is parallel to axis f image You now know the position of the same point on the image image is: real inverted smaller S > 2f object object 111 += S S′ f S′ M =− S f 2f 2f image S S’ f S = 2f object 111 += S S′ f S′ M =− S i...
