Physics: Optics Ch 58.1 Refracting Surfaces (3 of 22) Refraction at a Flat Surface: Example

In this video I will find the distance of the image, s'=?, of the fish (virtual) when the observed fish (object) through a fish tank (flat surface) where n1=1.33 (water) and n2=1 (air).

Next video in this series can be seen at:

You are the best at explaining. This helped very much.

How is this formula derived from n1/a+n2/b = n2-n1/R
