SHADOWS: dark=umbra, light=penumbra ? ? PINHOLE CAMERA: PLANE MIRRORS: plane mirror makes virtual, right-side up (erect) images law of reflection: angle of incidence equals angle of reflection CURVED MIRRORS: convex: Object placed anywhere: virtual, upright, smaller image formed behind the mirror. Here the image distance, di, is negative since its on the opposite side of the mirror. A convex/diverging mirror has a negative focal length. Concave: Object past focal point(to the left): real, inverted, in front of mirror Object at focal point: no image Object in front of focal point: virtual upright image behind mirror, negative image distance Center of curvature= 2 times the focal distance (C=2f)
