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. WebThe sign conventions for the given quantities in the lens equation and magnification equations are as follows: f is + if the lens is a double convex lens (converging lens) f is - if the lens is a double concave lens (diverging lens) d i is + if the image is a real image and located on the opposite side of the lens.
