Sign conventions of mirror
WebAccording to the new cartesian sign convention, pole of the mirror is taken as the origin. All the measurements of object distance, image distance and the focal length are recorded from the pole of mirror. All measurements are positive in the direction of incident rays whereas that and its opposite measurements are taken as negative. WebJan 9, 2016 · 1 Answer. Sorted by: 1. In starting it is futile, but if you use many mirrors, you will get mad. Actually, you have derived your formula in a particular case, say when image is behind the mirror. To extrapolate it to other cases, you say that you could have used opposite sign of image distance. But this will create different formulas for ...

WebSep 12, 2024 · Sign conventions for lenses. To properly use the thin-lens equation, the following sign conventions must be obeyed: \(d_i\) is positive if the image is on the side opposite the object (i.e., real image); otherwise, \(d_i\) is negative (i.e., virtual image). \(f\) is positive for a converging lens and negative for a diverging lens.
