[@sriharshini1749]

Hello sir, what is the use of optical bench? Plz anyone answer me

[@vandanasgreenheaven]

The lens formula is
f=uv/(u-v)

[@ashwin7071]

Vandana Verma He has applied sign convention. -(-1/u) = 1/u

[@Anonymous-pq4mr]

No... For Convex lens and Real image, it is f=uv/(u+v)

thank u sir...can u tell me which is your mother toungue.....mine is kannada from karnataka

[@abhirupmitra1708]

the focal length formula is f=uv/v-u is suppose!! for a lens

[@srishtigupta2795]

The formula is correct for convex lens since due to sign convention u is negative so if you will put it in the Selena formula,that will turn out to be f=uv/u+v.
