What is Spectrum of light?

A spectrum of light is like a rainbow made from all the colors hidden inside white light.

Imagine you have a flashlight that shines white light, it looks plain at first. But if you shine that light through a glass prism, something amazing happens: the light spreads out into different colors, just like a rainbow. This spread-out collection of colors is called the spectrum.

Think of white light as a group of tiny color friends traveling together. Each friend has its own color: red, orange, yellow, green, blue, indigo, and violet. When they go through the prism, they slow down at different speeds, kind of like how some kids walk faster than others in a race, which makes them spread out.

This is why rainbows happen after it rains! Water droplets act like tiny prisms, splitting sunlight into its spectrum. You can also see this effect when you shine light through a CD or a glass of water, both can turn white light into colorful patterns!

So the spectrum of light is just all the colors hiding inside the white light we see every day.
