Introduction to Dispersion of Light

Have you ever seen a rainbow in the sky? When does it occur? Why?

Which light do you think includes all colours? Explain.

How can you split the white light into colours?

Have you ever heard the term "dispersion"? What does it mean?

Try to answer the above questions but do not consider this as an obligation. It is OK even if you don't known the answers. You will have chance to know them by the end of this tutorial.
