Dispersion of light

प्रकाश का विक्षेपण

In this Class 10 Science topic from “The Human Eye and the Colourful World,” students learn how white light separates into its constituent colours when it passes through a glass prism. They study that different colours bend by different amounts because their wavelengths and refractive indices differ, forming a spectrum commonly described as VIBGYOR. The topic connects dispersion with the formation of rainbows and helps explain how refraction produces the colourful effects observed in nature.
