Refractive index increment dn/dc values - Materials Talks
In light scattering a crucial parameter that appears together with the Rayleigh Ratio RΘ is the refractive index increment, also known as "dn/dc". Typically, Kc/RΘ is plotted versus concentration to extrapolate to zero concentration. This is how we can obtain the molecular weight in a batch SLS ( static light scattering) measurement.

Eyeglasses for Refractive Errors | National Eye Institute
Eyeglass lenses work by bending light — just like the lens and cornea in your eye. The eyeglass lens bends light to make it focus correctly on your retina (the light-sensitive layer of tissue at the back of the eye). Different eyeglass lenses can correct different errors caused by problems with the cornea, lens, or shape of the eye.

On the distribution of protein refractive index increments
The protein refractive index increment, dn/dc, is an important parameter underlying the concentration determination and the biophysical characterization of proteins and protein complexes in many techniques. In this study, we examine the widely used assumption that most proteins have dn/dc values in …

Refractive index contrast
Refractive index contrast, in an optical waveguide, such as an optical fiber, is a measure of the relative difference in refractive index of the core and ) and n2 is the refractive index of the cladding.

Complex refractive index. > A linearly polarized wave with the vacuum wavelength $\lambda_0$ falls perpendicular on a material with the complex refractive index $\bar{n}=1.5+i\cdot 0.15$ with that wavelength. > > Aft...
Assuming no dispersion, the electric field amplitude of the wave in the initial vacuum is $$E(z) = E_0 e^{i 2 \pi (z - c t)/\lambda_0} $$ so that the original value of the intensity is $|E_0|^2$. The (intensity) transmission coefficient into the material is $$T = 1-\left |\frac{\hat{n}-1}{\hat{n}+1}...

Compound refractive lens
A Compound refractive lens (CRL) is a series of individual lenses arranged in a linear array in order to achieve focusing of X-rays in the energy range For all materials the real part of the refractive index for X-rays is close to 1, hence a single conventional lens for X-rays has an extremely long focal

Given the following information about the speed of light: Speed of light in vacuum which has a refractive index of 1 is 300Km/sec Speed of light in water which has a refractive index of 1.3 is 225Km/sec Speed of light...
From the information given we can see the light of speed is inversely proportional the refractive index of the medium. We can estimate the speed of light in glass as speed of light in vacuum divided by the medium's refractive index.

Simple question related to Snell's law There are two media and they are stacked vertically like the figure below. Medium 1 - height : h, refractive index : $n_1$ Medium 2 - height : h, refractive index : $n_2$ ...
I belive the answer is given by $$ d = h [\tan \theta_1 + \tan \theta_2]$$ each term giving you thee horizontal distance travelled for each medium. Now, according to Snell's law $$\frac{\sin \theta_1}{\sin \theta_2} = \frac{n_1}{n_2}$$ so $$\theta_2 = \arcsin \left(\sin \theta_1 \cdot \frac{n2}{n1}\...

Refractive index - Wikipedia
Refractive index. In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. The refractive index determine how much the path of light is bent, or refracted, when entering a material. This is described by Snell's law of refraction ...

On the Distribution of Protein Refractive Index Increments
The protein refractive index increment, dn/dc, is an important parameter underlying the concentration determination and the biophysical characterization of proteins and protein complexes in many techniques.In this study, we examine the widely used assumption that most proteins have dn/dc values in a very narrow range, and reappraise the prediction of dn/dc of unmodified proteins based on their ...
