Sign orientation in mirrors and lenses
WebThe sign convention we're using is that objects, images, and focal lengths in front of the mirror are gonna be positive. Anything behind the mirror is gonna be negative. And you could use the magnification equation to figure out how tall the image is gonna be relative to the object by taking negative the image distance over the object distance. WebMany factors impact the effectiveness of an individual sign. We have identified 5 of the most important: size, sign angle, location, luminance, contrast. This video introduces and …
