A monochromatic beam of light does not split when it passes through a prism while a beam of white light does. How are the two cases different from each other?Explain.
Dear Student ,
When a beam of monochromatic light passes through a Prism , it will refract but it does not split or disperse. This is because it is a beam of single wavelength.
However , In case of white light , it will show dispersion as it is comprised of 7 different colours (VIBGYOR) , each colour having different wavelength inside prism.
Hope this will clear Your doubt!
but in case of white light which consist of seven colour means 7 different wavelength so velocity for different wavelength is different so they split after passing from prism.
