Light refraction index equation

AI Thread Summary
The equation R = [(n1-n2)/(n1+n2)] has been both theoretically derived and experimentally verified in relation to light refraction index and reflection. It can be mathematically derived from Fresnel's equations, which describe how light behaves at the interface between different media. The equation provided is a special case of the more general reflection coefficient formula, R = [(n1-n2)/(n1+n2)]². Resources were shared for further understanding of the derivation and applications of these equations. This discussion clarifies the foundational principles behind the light refraction index and its reflection properties.

Is the following equation which relates to light refraction index and the amount which bounces back been proven experimental or theoretically(mathematicaly)?

R = [(n1-n2)/(n1+n2)]
 
Science news on Phys.org
Yes to both, It can be derived from principles and has been verified experimentally.
 
Thanks, now I know.
Can you also tell me how it was done mathematically?

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
