Waves and phase difference Two identical waves with wavelength $$617\,[\text{nm}]$$ and the same phase constant, pass through $$2.2\,[\text{mm}]$$ of different glass materials. One material's refractive index is $$1.8$$, while the other material has a refractive index of $$1.2$$. After both waves exit from the respective materials, the magnitude of the phase angle difference in units of radians between the two waves is:
