WebExamine the situation to determine that image formation by a lens is involved. Step 2. Determine whether ray tracing, the thin lens equations, or both are to be employed. A sketch is very useful even if ray tracing is not specifically required by the problem. Write symbols and values on the sketch. Step 3. WebNov 5, 2024 · The simplest case is where lenses are placed in contact: if the lenses of focal lengths f1 and f2 are “thin”, the combined focal length f of the lenses is given by. (24.3.3) 1 f = 1 f 1 + 1 f 2. Since 1/ f is the power of a lens, it can be seen that the powers of thin lenses in contact are additive.
