Equation for converging lens

WebThe thin lens equation quickly provides the relation between di, do, and the focal length f. It can be derived from a geometric analysis of ray tracing for thin lenses and is given by \frac {1} {\text {d}_\text {o}}+\frac {1} {\text {d}_\text {i}}=\frac {1} {\text {f}} do 1 + di 1 = f1 . WebThe focal length of a thin converging lens is 10 c m. Calculate the values of (i) image distance and (ii) magnification of the lens when the object distance is 21.5 cm. Choose an answer A (i) 18.7 cm and (ii) − 0.870 B (i) 37.4 cm and (ii) − 0.435 C (i) 9.35 cm and (ii) − 0.522 D (i) 56.1 cm and (ii) − 0.348 Show solution Keep Learning
