Dispersion is the separation of white light into separate colors by differences in wave amplitude. Amplitude of the wave can be calculated by the distance from the center to the top of the wave.

Answer:

option (A)

Explanation:

The splitting of white light into its seven constituent colours is called dispersion. As the white light contains seven colours and the order of increasing wavelength is given by

Violet < Indigo < Blue < Green < Yellow < Orange < Red

All the colours have different wavelength and hence all the cours have different angle of deviation.
