(d) The focal length of each part will be 2f.A convex lens of focal length f cut into parts first horizontally and then vertically. Find the focal length of part A of the lens, as shown:
The pressure tube is made up of one or more chambers, with only the central one pressurised. A metal or plastics material ring encircles the pressure tube and lens and hold them under tension. The focal length of the lens is adjusted by opening one or more of the valves, thus altering ...
