Focal length formula mirror

WebA concave mirror is the type of curved mirror whose reflected surface is inwards i.e. it is facing towards the focal point of the mirror. The images which are formed in this mirror are real and inverted in nature. The sign of the focal length in this mirror is negative. The focal length of the concave mirror can be derived as shown. WebFocal length ≈ curvature radius / 2. The equations are: 1/o + 1/I = 1/f. F ≈ r/2. Where: o: Object distance. I: Formed image distance. f: focal length. r: Curvature radius.
