Question

Thin lens I.-Convex Lens The purpose of this exercise is to determine the focal length of a converging lens, and its magnification as a function of its object distance. Theors Parallel rays incident on a converging lens, focus at a point called the focal point. The distance of the focal point from the lens is the focal length. converging lens tocal point (F) light rays focal length For a near object, the object distance p, the image distance q, the focal length fare related by the lens equation, which is . . . . . 1 Pagos. 2 of 5 Words: 488 of 492 Print Layout View

Explanation / Answer

This is just the experiment to calculate focal length of lens and image height.

If light will enter parallel to lens then u =0 then v =f so just y seeing image distance focal length of lens can be found out.

For 2 part we are firstly measuring the height from the screen of the image and then calculating it using theoratical formula for focal length and image height.

And then same experiment is there for concave lens.
