Explain Dispersion Of light ...
Need Explanation
​

Answer 1

‘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. The white light splits into its constituent colors at various frequencies and various angles.

✨The phenomenon of splitting up of light unto its. constituent colours on passing through a prism is called DISPERSION OF LIGHT✨.

⭕A prism is made up of a transparent medium bounded by two plane surfaces inclined at an angle.

✳️It consists of two plan refracting surfaces. When white light (from sun or tube light) is incident on one refracting surface of the prism, the light splits up into constituent Colours = Violet, indigo, blue, green, yellow, orange, and red.

The band of Colours obtained is called ⚫Spectrum of light. The spectrum of light (VIBGYOR) can be seen on a screen placed on the other side of the prism.
