Physics: Optics Ch 58.1 Refracting Surfaces (11 of 22) Refraction with (+) Radius of Curvature

In this video I will find the locations of the images s1'=?, s2'=?, and s3'=? of 3 objects O1, O2, and O3 (on the convex side of the boundary, or positive radius of curvature) at distances of s1=15cm, s2=20cm, and s3=25cm, respectively.

Next video in this series can be seen at:

Sir can you explain about non integral functions. Why some functions are non- integrable.
