What is dispersion please give answer
Answers
the white light pass through the prism called dispersion
Hope it helps
Hi, Here is your answer
====================
Dispersion of light is a phenomenon of splitting of white light in to its component colours.
In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency, or alternatively when the group velocity depends on the frequency. Media having such a property are termed dispersive media.
When a light ray enters one refracting surface of the prism, it bends towards the normal and when it emerges out of the other refracting surface it bends away from the normal.
Rainbow is the natural phenomenon in which dispersion takes place. The cause of dispersion is that sun light consists of seven constituents (colours namely violet, indigo, blue, green, yellow, orange and red popularly referred to as VIBGYOR) that have different refractive index with respect to a medium. The wavelength of each colour is different that causes the difference in velocity of the corresponding light when passing from one medium to another.
