Convex lens - Determination of Focal length by plotting a graph between u Vs v and 1/u Vs 1/v

[@moulishwarrr4469]

Clearly explained sir!

[@manikandaninstituteofphysics]

Thanks

[@arunkumarjanakiraman6167]

Sir lens formula 1/v-1/u =1/f .. but you used mirror formula sir uv/u+v. Kindly explain sir

Very well explained sir🙏🏻

What is the standard value of focal length for convex and concave length?

[@manikandaninstituteofphysics]

We can't say the standard value of a focal length it depends on the radius of curvature of a given lens. Most of the lenses have a focal length of 15cm or 20 cm.

[@JustinaAwogbemi]

This is well explained
Bit what if it is a graph of 1/u against 1/v

[@manikandaninstituteofphysics]

You will get a similar result. Since focal length is constant.
