Question

what do you mean by dispersion? Name the different colours of light in the proper sequence in the spectrum

Answer 1

Dispersion is the splitting of white light or any composite light into its constituent colors.
In spectrum, the proper sequence is VIBGYOR, that is, from bottom it is, Violet, Indigo, Blue, Green, Yellow, Orange and then Red

Answer 2

Answer:

‘Dispersion of Light’ can be defined as the splitting of white light when it passes through a glass prism into its constituent spectrum of colors (i.e. violet, indigo , blue, green, yellow, orange and red). Dispersion figuratively means ‘distribution’ and hence that’s exactly what is happening in the picture above.
