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. … WebThe +/- Sign Conventions. The 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.

Now that we know how to find the focal point of a lens using a distant object, we can see what happens to light rays from objects that are closer to the lens. Let’s say we have a cat standing on one side of a converging lens. We know that there are two focal points, one on each side of the lens, and that ...
WebWhile dealing with reflection of of light by spherical mirrors we follow a set of sign conventions called the "NEW CARTESIAN SIGN CONVENTION". in this convention, the pole (P) of the mirror is taken as the origin. The principal axis of the mirror is taken as the x-axis of the coordinate system. The conventions are as follows:-
