Concept of multiple focal length and variation of focal length with surrounding medium
Lesson 14 of 16 • 9 upvotes • 9:14mins
Himanshu Sachdeva
In this lesson we have discuss the concepts related to multiple focal length of a lens and behaviour of a lens when it is dipped inside a liquid. We have also discussed the concept of a convex lens becoming diverging and concave lens becoming converging when did in a liquid of refractive index greater than that of material of units.
