Question
State the lens formula. Is the same formula applicable to both convex and concave lenses?
Solution
Lens formula:
The lens formula is a mathematical relation between the object distance u, image distance v and focal length f of a spherical lens.
This relation is:
In words, we can say that
This formula is applicable to both convex and concave lenses.
