Question

Does light show dispersion in every transparent medium?​

Answer 1

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.
