What Does It Mean? 🤔
Let's learn together
🌈
White light looks like it has no color at all. But it is actually a mix of every color of the rainbow, all blended together! This full range of hidden colors is called the light spectrum.
Freddy showed this by shining sunlight through a glass of water onto a piece of paper. A whole rainbow appeared on the paper, even though the sunlight going in looked completely white!
Each color in the light spectrum bends by a slightly different amount when it passes through water or glass. Red bends the least and violet bends the most, which is exactly why the colors spread apart into a rainbow.

👨👩👧 Teaching Tips
Use a real prism or even a glass of water in sunlight to show the spectrum live — seeing the rainbow appear is far more memorable than describing it.
🏫 Classroom Ideas
Have students predict which color they think will bend the most before showing them a prism demonstration, then compare predictions to what actually happens.
