Question

For a particular glass lens F=-2m,only this much data was provided to a students he was told to calculate the power of lens and to find out types of lens given to him ,his answers must be

Answer 1

Answer:

• The thin lens equation quickly provides the relation between di, do, and the focal length f. It can be derived from a geometric analysis of ray tracing for thin lenses and is given by 1do+1di=1f 1 d o + 1 d i = 1 f . The magnification m of an image is the ratio between the image and object height (hi/ho).
