SUMMARY

Dispersion in a wave refers to the phenomenon where a wave signal becomes warped over time because different components of the wave travel at varying velocities. The discussion identifies two primary forms of dispersion: wavelength dispersion, which occurs due to differences in the wavelengths of wave components, and amplitude dispersion, which arises from variations in the amplitudes of those components. Understanding these forms is crucial for analyzing wave behavior in various applications.

Effectively, it means how a wave signal becomes warped over time due to that different components of the wave travel with different velocities.

The two typical forms of dispersion is dispersion due to typical wave-length differences among wave components, and dispersion due to typical amplitude difference among wave components.
 
thanks! :)
