Hey mate!!!
Dispersion
Any phenomenon associated with the propagation of individual waves at speeds that depend on their wavelengths is called dispersion.
Ocean waves, for example, move at speeds proportional to the square root of their wavelengths; these speeds vary from a few feet per second for ripples to hundreds of miles per hour for tsunamis.
A wave of light has a speed in a transparent medium that varies inversely with the index of refraction (a measure of the angle by which the direction of a wave is changed as it moves from one medium into another).
Any transparent medium—e.g., a glass prism will cause an incident parallel beam of light to fan out according to the refractive index of the glass for each of the component wavelengths, or colours.
Dispersion is sometimes called the separation of light into colours, an effect more properly called angular dispersion.
The order of colours will be VIBGYOR. Here red is the least deviated colour and violet is the most deviated colour.
Hope this helps you!!!
Answer:In statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed. Common examples of measures of statistical dispersion are the variance, standard deviation, and interquartile range.
