Snell’s Law explains light refraction at material boundaries, a principle crucial to fiber optics, lens design, and advanced ...

is. Light of frequency \(4.6\times 10^{14}Hz\) travels at a speed of \(1.24\times 10^{8}ms^{-1}\) in diamond. Calculate the refractive index of diamond for this colour of light.

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 ...
