WebSign convention in the case of a convex mirror: Since, object is always placed in front of the mirror hence the sign of object is taken as negative. Since, the centre of curvature and focus lies behind the convex mirror, so sign of radius of curvature and focal length are taken as + (positive) in the case of convex mirror. WebFeb 26, 2007 · IMHO, it's okay to switch signature conventions in private or among friends. However, for presentations (research or pedagogical), one should stick to one and be consistent. (I can't imagine switching sign conventions in [say] optics problems.) Let's not forget other sign-conventions associated with the index positions in Riemann, etc...
