May 20, 2020 · From this formula, it seems to be that we are substituting the angle of refraction as the angle of incidence, therefore $\frac {\sin (90)} {\sin (C)}$, but why can we do this?

Can some one please explain in simple words that what is effective refractive index? How it is different from the refractive index? And how we can calculate the effective refractive index?

What is polytropic index? What is the connection between it and work of an adiabatic system? I tried surfing but didn't able to find a proper answer for that.

Nov 12, 2020 · How does the refractive index of air rely on the temperature? Is there a theoretical derivation of it?

Jan 8, 2022 · I'm currently trying to calculate the effective refractive index neff n e f f of waveguides using the (measured) group index ng n g and the wavelength λ λ. I started with …

Dec 2, 2022 · Does that mean that diamond is a linear homogeneous medium, but water isn't? Is that the reason why the formula does not work for diamond? If so, then why is water not a …

These, the index of refraction and the inverse dielectric function are therefore the most appropriate quantities to measure. As a further reference, I recommend the book …
