Question

Withe light becomes a spectrum of seven colored lights after passing through a prism

Answer 1

Answer 2

After passing through a prism, white light is spread out into it's spectrum, which includes all of the thousands of colors perceptible to the human eye. In the third grade, we learn seven names for colors that roughly span the visible range. But the truth is that there are hundreds of other colors between each pair of those names.
