Optics sign conventions

WebA sign convention must be defined, understood, and followed. The Cartesian sign convention will be used in this course. This is NOT the same as used in Halliday and Resnick, but is used in many specialist optics textbooks. In this case we have:- 1) Light initially propagates from left to right. WebSep 12, 2024 · To keep track of the signs of the various quantities in the mirror equation, we now introduce a sign convention. Sign convention for spherical mirrors Using a consistent sign convention is very important in geometric optics. It assigns positive or negative values for the quantities that characterize an optical system.

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 ...
