HI,
Welcome to your own YouTube channel "The School".

This is Ajeet verma from IIT Dhanbad.
In this Video, We have described the basic introduction of Lens. In Class 12th, Lens is one of the most important topic in the chapter ray optics and optical instruments. We have explained the types of lens such as convexo-convex lens, plano-convex lens, concavo-convex lens, concavo-concave lens , plano-concave lens and convexo-concave lens.

Also we have have discussed the complete derivation of Lens maker's formula, lens formula,
Basically, Lens formula is the relation between object distance, image distance and their focal length

We have covered all possible cases such as (1) Lens formula, when medium is same on both side of lens. case (2) When media on both side of convex lens are different.
