i have no clue about the second part..
A dispersive medium is a material in which the speed of a wave depends on its frequency or wavelength. This means that different frequencies of the same wave will travel at different speeds through the medium. This can cause the wave to change shape or spread out over time.
Common examples of dispersive media include water, air, and glass. These materials exhibit different speeds for different frequencies of light and sound waves, causing dispersion to occur.
In dispersive media, waves will disperse or spread out over time, causing them to have different shapes or frequencies compared to when they first entered the medium. This is due to the varying speeds of different frequencies of the wave.
The equation for wave speed in a dispersive medium is c = λf, where c is the speed of the wave, λ is the wavelength, and f is the frequency of the wave. This equation shows that the speed of the wave is dependent on its frequency.
There are various methods for controlling or manipulating waves in dispersive media, such as using lenses or filters to adjust the speed of specific frequencies. Additionally, changing the properties of the medium itself, such as temperature or pressure, can also affect the behavior of waves within it.
