Question

What is despersion of light? ​

Answer 1

Dispersion of light :-

The process of splitting up of white light into constituent colours VIBGYOR ( Violet, indigo, blue, green, yellow , orange, red )

___________________________

Cause of dispersion:-

• Every colour has its own characteristics wavelength/ frequency. Different colours move with same speed in air /vacuum . But their speeds in refractive media like glass are different. Therefore, refractive index of the medium for different colours is different. As a result, different colors undergo different deviation on passing through the prism . hence, different colours emerge from the prism along different directions.
