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. WebJan 9, 2016 · optics - The sign of a focal length - Physics Stack Exchange The sign of a focal length Ask Question Asked 7 years, 3 months ago Modified 7 years, 3 months ago Viewed 387 times 2 We know that for converging lens, f > 0 , for diverging lens, f < 0. But for many materials I have read so far, it says that: "the focal length of a concave lens is 8 cm."
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 ...

WebFeb 26, 2007 · IMHO, it's okay to switch signature conventions in private or among friends. However, for presentations (research or pedagogical), one should stick to one and be consistent.
