Explanation: When light waves propagate through and around objects whose dimensions are much greater than the wavelength of the light,
My textbook, Fundamentals of Photonics, 3rd edition, by Teich and Saleh, says the following:
When light waves propagate through and around objects whose dimensions are much greater than the ...

Variation of Refractive index
We know that refractive index, for any medium,
$$n=1/\sqrt{\epsilon\mu}.$$
Also, according to Cauchy's relation
$$n=A+B/\lambda^2,$$
where $A$ and $B$ are constants related to the medium.

Is optical path length (OPL) usually in units of length, or wavelength?
When I do calculations, I usually define optical path length (OPL) of a path as the integral of index $n$ along a path divided by the vacuum wavelength, so that I can get the phase easily. So for a ...

Optics: finding total power of a system, including wavelength
Specifically I need to create an ABCD matrix given 2 radii of curvatures, the thickness of the lens, type of glass (BK7) and a given wavelength. I will have to figure this out eventually, so help ...
