\nWhen a beam of white light passes through a prism, it is dispersed into its seven constituent colours due to the difference in the refractive index of the prism material for different wavelengths of light. The extent to which a colour is deviated depends on the refractive index for that colour; a higher refractive index leads to a greater deviation.
\n<\/section>\n
\nThe refractive index of a material is highest for shorter wavelengths (like violet light) and lowest for longer wavelengths (like red light). Consequently, violet light undergoes the maximum deviation, while red light undergoes the minimum deviation.
\n<\/section>\n
\nThis phenomenon of splitting white light into its constituent colours is called dispersion. The band of seven colours produced is called the spectrum. The acronym VIBGYOR represents the order of colours in the spectrum from maximum deviation (Violet) to minimum deviation (Red). A hollow prism filled with water still functions as a prism made of water, exhibiting the same dispersion property.
