Mirrors Law of Reflection I = R (Angles measured with respect to Normal) Image size h i Object size h o Object distance d o Image distance d i h o h i d o d i
Conventions: h and h are positive if the objec h o and h i are positive if the object (image) is above the optical axis. d o and d i are positive if they are on the reflective side of the mirror (in front of the mirror) fis positive if the focal point is on the reflective side of the mirror the side of the mirror. (concave mirror) Magnification M = h / h O = - d / d O I I Mirror Equation 1 / d I + 1 / d O = 1 / f
