Splitting of white light into its seven constituent color I.e. vibgyor.
The sploting of white light when

When light particles collide with different particles and scater in different direction is known as scattering of light
Splinting up of light rays into its component coloured is known as scattering of light
The splitting of white light into seven colours

According to lord Rayleigh, if wavelength is greater than x,then intensity of scattered light is inversely proportional to 4th power of wavelength.

The spilitting of white light into VIBGROR
Spliting into its constituent colors
In a vibgyor form
Splitting of seven colour.

Thanks both of you.
But in Collions
And its due to Tyndall effect
Dispersion of light
The phenomena due to light rays gets scattered by collision of particles present in atmosphere and gives its spectrum
