You will learn the graphical and mathematical tools you need to calculate image size and location for thin lens and mirror systems. This foundation is essential to build more complex optical systems. 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.
