Question

Explain the phenomenon of dispersion of white light and write the cause of dispersion

Answer 1

split of white light into seven colours in pattern of VIBGYOR is known as dispersion of white light..

it is because the angle of refraction of light of different colour is different when passing through a glass prism

Answer 2

Answer:

Dispersion is defined as the phenomenon of splitting of white light into different colours on passing through a transparent medium such as prism. When white light is passed through a prism, it splits into seven colours. It is observed that the colours are in the following order:

Violet (V), Indigo (I), Blue (B), Green (G), Yellow (Y), Orange (O) and Red (R). The order of colours can be remembered by the acronym VIBGYOR. This coloured band is called spectrum of white light.
