I just thought of something else, would it be a viable option to substitute the value of object distance as something radically far-off, such as 50m, which is 5000cm? Apply this to the thin lens equation for focal length for one of the lenses, and I would get almost the exact value of the actual...
Hmm...I've heard of that + looked a bit into it, but it wasn't a method taught in class so I doubt it'll be accepted for the project...furthermore, I don't have measurements for the required factors of R1 and R2.
Just to clarify, I already have the focal lengths of both double convex lenses...
From what I recall, determining the focal length of a double convex lens just involves an infinite light source and holding the lens close to an image-capturing surface such as a wall and adjusting the distance until the image is at its sharpest...the distance from the lens to the surface is the...
