Image and sign convention in lens
WebSign convention in the mirrors prioritize that the object should be kept on the left side of the mirror and the distances of the objects from the mirrors are always calculated from the pole of the mirror. The distance measured towards the incident ray is considered positive and opposite to the incident ray is taken as negative in physical science. WebThe distance from the lens to the focal point is called the focal length. For converging lenses, the focal length is always positive, while diverging lenses always have negative …

WebLens Formula. If the distance of object from the optical centre of the lens is u, distance of image from the optical centre is v and focal length of the lens is f, then the relationship between u, v and f for lens is: 1/f = 1/v - 1/u. This is called lens formula. Focal length for convex lens is positive, for concave lens it is taken negative.
