Question

Newton pass narrow beam of white light on a glass prism and observed that it can split into seven colours name the natural phenomena to this phenomena​

Answer 1

Answer:

this know as dispersion of light because white light is mixer of 7 colors with different frequencys so they have different angular dispersion

Answer 2

The phenomena based on the Spectrum of white light: The band of seven colours formed when a beam of white light is passing through a glass prism.

Explanation:

Sir Isaac Newton discovered that white light consists (seven colours). He found that if a beam of white light is passed through a glass prism then it will split into seven colours. Like a red, orange, yellow, green, blue, indigo and violet (VIBGYOR).

The spectrum of white light: The group of seven colours formed when a beam of white light is passing through a glass prism is called a spectrum of white light.

Dispersion of light: The splitting of white light passion through a transparent medium into seven colours is called dispersion of light.

The dispersion of white light occurs  when the light passing through the transparent medium, the angle of refraction of lights of different colours is different.  

For example, In white light spectrum red colour deviates least and is formed at the upper part of the spectrum and violet colour is deviated maximum and is formed at the bottom of the spectrum.
