Question

Obtain the lens formula for spherical lens.Write answers of the given question.

Answer 1

Gaussian lens formula. In the preceeding applet we introduced Gauss's ray diagram, which allowed us to find for any point in object space the position in image space where rays leaving that point reconverge (i.e. come to a focus). ... It is beyond the scope of this applet to derive the Gaussian lens formula.

Answer 2

✨✔️✔️ HERE IS YOUR ANSWER....

✔️ Relationship between object distance (u), image distance (v) and the focal length (f) is referred to as lens formula.

✔ ️$\frac{1}{v} - \frac{1}{u} = \frac{1}{f}$
