Description: Please note, this figure shows the ideal case of no dispersion, which means that the refractive index n is independent of the wavelength λ{\displaystyle \lambda }. In reality n will depend on λ{\displaystyle \lambda } and hence the wave front (governed by group velocity) will no longer be perpendicular to the direction of the radiation (governed by phase velocity).
