Critica angle:

$\overline{){{\mathbf{\theta}}}_{{\mathbf{c}}}{\mathbf{=}}{\mathbf{s}}{\mathbf{i}}{{\mathbf{n}}}^{\mathbf{-}\mathbf{1}}{\mathbf{\left(}}\frac{\mathbf{\eta}\mathbf{2}}{\mathbf{\eta}\mathbf{1}}{\mathbf{\right)}}}$

η_{2} = η_{air} = 1

η_{1} = η_{incident}

θ_{c,red} - θ_{c,violet} = sin^{-1}(1/η_{red}) - sin^{-1}(1/η_{violet})

Consider a diamond surrounded by air.

A) By how much (in degrees) do the critical angles for total internal reflection differ for red (660 nm) light compared to violet (410 nm) light?
