Which effect occurs during electromagnetic wave propagation through a dispersive medium?

💡 Explanation

When an electromagnetic wave propagates through a dispersive medium, wave dispersion occurs because the refractive index varies with frequency, causing different frequency components to travel at different phase velocities. Therefore phase velocity becomes frequency-dependent, rather than amplitude increase, constant polarization, or equal group and phase velocities all of which require different conditions.
