When composite white light with seven colours as constituents enter into triangular prism, then different colours get refracted at different angles because of the different refractive index value of glass for different colours. Refractive index is defined as the ratio of the speed of light in free space to that in the glass medium. As the speed of the different colour differ, the refractive index varies. Hence they have different angle of refraction. So all the colours have been split up. As we use a triangular prism, as the refracted colours fall on the other face of the prism, once again separation becomes possible. Hence the phenomenon of dispersion.
But this will not be possible when we use a rectangular glass slab. So triangular prism is essential to have dispersion.

Why glass slab does not produce dispersion?
Glass slabs do not produce dispersion because dispersion requires different materials with varying refractive indexes to separate light into its different spectral components. Glass slabs are made of the same material throughout and do not have the necessary variation in refractive index to cause dispersion.
What is the cause of London dispersion forces, and what are they not caused by?
London dispersion forces are caused by temporary fluctuations in electron distribution within atoms or molecules. They are not caused by permanent dipoles or hydrogen bonding.
What are types of dispersion?
the three types of dispersion are: 1. Intermodal Dispersion 2. Chromatic Dispersion 3. Waveguide Dispersion

What are the types of dispersion compensation?
The types of dispersion compensation are chromatic dispersion compensation, polarization mode dispersion compensation, and non-linear dispersion compensation. Chromatic dispersion compensation corrects for dispersion caused by different wavelengths of light traveling at different speeds. Polarization mode dispersion compensation addresses differences in travel time for different polarization states of light. Non-linear dispersion compensation manages dispersion that varies with the intensity of the light signal.
Why does glass slab not cause dipersion?
Glass slabs do cause dispersion of light, but it may not be as prominent as in other materials due to their relatively low refractive index compared to materials like prisms. Dispersion is the phenomenon where different colors of light are spread out due to their different wavelengths. In glass, the dispersion effect can be seen at the edges of the slab or in certain conditions where the light path is longer.
