Hello
I'm trying to solve a problem where I'm asked to find the optimum index of refraction for an antireflective coating on a piece of glass. In trying to derive an equation for it I keep coming across this in the internet (where 1,0, and s should be subscripts)
n1=sqrt(n0ns)
where n1 is...
Thanks for your reply. I had a look at this, but don't understand how you can use the first image as a virtual object for the slab of glass, because it will be inside it. Also, we aren't told the thickness of the glass slab, I think because it is infinitely thick so it doesn't matter.
Any ideas?
1. An object (height o) is placed at an object distance S in front of a converging lens. The lens is placed at a distance d<Si (image distance) in front of a very thick glass plate (index of refraction n, thickness larger than image distance). The surface of the glass plate is perpendicular to...
