Find the focal length of the convex lens using uv method
Dear studentPlease find the link belowhttps://www.askiitians.com/iit-jee-ray-optics/determination-of-focal-length-of-convex-lens-u-method/Regards
The relation between u, v and f for a convex lens is,v-1 + u-1 = f-1Using the proper sign convention, u is negative, u negative, v and f are positive. So we have,Comparing with y = mx + c, graph between v-1 & u-1 is negative with slope –1 and intercept f-1 .The corresponding graph is as shown in figure.Proceeding in the similar manner as discussed in case of a concave mirror the focal length of the lens can be calculated by measuring the coordinates of either of the points A, B and C.u–v GraphThe u versus v graph is a hyperbola as shown in figure. By measuring the coordinates of point C whose coordinates are (2f, 2f) we can calculate the focal length of the lens.
