WebSign convention is a set of rules that standardises a set of signs for the distances that are calculated in ray diagrams for the purpose of mathematical analysis of image formation. Distances and the signs are always taken from the pole of the spherical mirror. The distance measured along the direction of the incident ray (measured from behind ... WebThe sign conventions for the given quantities in the mirror equation and magnification equations are as follows: f is + if the mirror is a concave mirror f is - if the mirror is a convex mirror d i is + if the image is a real image and located on the object's side of the mirror. eagle locksmith northern beaches
