We can also use wavelengths to calculate refractive index. By substituting \(v_{1}=f\lambda _{1}\) and \(v_{2}=f\lambda _{2}\) into \(n=\frac{v_{1}}{v_{2}}\) then ...
Plot a graph of sine of angle of incidence (y axis) against sine of angle of refraction. The gradient of this graph is the refractive index of the material of the semicircular block. So the ray ...
To measure the refractive index distribution in porcine eye lenses for two wavelengths from the visible spectrum: 532 and 633 nm, in order to determine whether there are any discernible wavelength ...
