Prism and Rainbow
Open to everyone until Tuesday, September 29
To keep it, print it while it is open.
White sunlight looks plain, but it is made of all the rainbow colors mixed together. When it passes through a glass prism, the colors spread out into a rainbow band.
In the picture
- The narrow white beam before the prism: a bright white ray
- The triangular glass prism: a clear glass block that bends the beam
- The broad rainbow band on the screen: the separated colors
Examples
- A rainbow in the sky after rain
- The shiny colors on a CD
Key takeaways
- White light contains all the rainbow colors.
- A prism bends each color by a different amount, so they separate.
