Question

What is dispersion of white light? What is the cause of this dispersion? Draw a diagram to show the dispersion of white light by a glass prism.

don't copy from Google​

Answer 1

Answer:

✨✨✨ A Spilliting of white light into seven constituent colours when pass through the prism is called /is known as dispersion of white light .✨✨

Explanation:✨

✨✨When a light pass through a prism it Distribute into seven colours which pattrens is VIBGYOR

✨ Where V is voilet

✨I is Indigo

✨B is Blue

✨G is Green

✨Y is yellow

✨O is orange

✨and R is Red

May this helps u

✨✨✨And one more thing this is Not from google....✌✨✨✨✨✨

Answer 2

Answer:

The splitting up of white light into its constituent colours is called dispersion. The colour sequence is given by the acronym V I B G Y O R – Violet, Indigo, Blue, Green, Yellow, Orange and Red. This colour pattern is called a spectrum. Dispersion takes place because the speed of light of different colours through a glass prism is different and so, refractive index, therefore, each colour bends (refracts) through different angles with respect to incident ray as they pass through a prism. The red colour has maximum speed in glass prism. So, it is least deviated while the violet colour has minimum speed so its deviation is maximum. Thus, the ray of each colour emerges along different paths and becomes distinct.
