Question

Two convex lenses (\(L_1\) and \(L_2\)) of equal focal length \(f\) are placed at a distance \(\frac{f}{2}\) apart. An object is placed at a distance \(4f\) to the left of \(L_1\) as shown in the figure. The final image is at:

• A. \(\frac{5f}{11}\) right of \(L_2\)
• B. \(\frac{5f}{11}\) left of \(L_2\)
• C. \(5f\) right of \(L_2\)
• D. \(5f\) left of \(L_2\)

Hint:

For multiple lens systems, calculate the image formed by the first lens and then treat this image as the object for the next lens. Use the lens formula for each lens to find the final image position.
