Dispersion
The splitting of white light into seven different constituent colours is called dispersion
Splitting white light into different colours is an optical phenomenon called Dispersion.
White light is composed of many colours. When these colours combine, they look white. One way of showing that white light is composed of different colours is to make white light pass through a glass prism. This splits up the white light into its constituent colours. I f you hold a screen in its path, you will see a band of colours. This band of colours is called the spectrum. Since it is visible to human eyes, it is called the visible spectrum.
The science instrument is called Prism. It actually does not bend light. It separates the light into seven different colours.

Traffic light colours have different shapes in order to inform the colour blind what colour the light is.
This Q&A is about light colours. Paint colours are substances, and different from light colours.If you hold up a glass prism to a beam of sunlight, you'll see the light form a rainbow of colours. This is called the spectrum. It consists of all the colours that make up "white" light.Although you might be able to see seven colours in the spectrum, the white light is really made up of three basic colours. These are called the primary colours because they cannot be made from any other colours. The primary colours of light are red-orange, green, and violet blue. The other colours you see in spectrums or rainbows are made by a mixture of the primary colours.When the naked eye looks at the spectrum, it can see three mixed colours, which are called secondary colours. The secondary colours in light are green-blue, yellow, and magenta-red. You can produce these colours by mixing the primary colours in certain combinations.
White is not a colour. It is sensed only by human eye. Actually white is a composite of many colours. Such a composite white light could be spilit up by using a triangular prism. This splitting of composite white light into its constituent colours is called dispersion.
We use prism to separate the 7 colors of the white light,,this is called white light dispersion because each one has different wave length and different energy.
Scattering of white light into its 7 constituent colours(VIBGYOR)is called dispersion of light and the band of 7 colours obtained is called Spectrum. Answer by VASU
