WebUsing the average value of your focal length measurements, calculate the image distance i if the object distance is 1.5 x your focal length (e.g, if your measured focal length were 10 cm, you would do the calculation for an object distance of 15 cm). For this arrangement, the image distance and linear magnification of the image are given by WebThe actual focal length of a lens generally differs from the nominal focal length marked on the lens. Lenses may vary ±5% from this nominal value. In multi-projector set-ups (e.g.: multi-image with several 35mm slide …
