Get a prism., Find a sunny place., Allow light to pass through the prism.
Step-by-Step Guide
-
Step 1: Get a prism.
There are different types of prisms that manipulate light in different ways.
You will need to get a refractive prism.
This type of prism will allow the light to bend in a way that splits it based on its wavelength.
In other words, shorter wavelengths bend more, and longer wavelengths bend less.
This creates a rainbow as the light exits the prism.You can buy a prism at a science supply store, a hobby store, or online.
Basic prisms are relatively inexpensive. -
Step 2: Find a sunny place.
The prism operates by splitting a beam of white light into its component colors.
To see this, you will need a high intensity light source.
Putting the prism by a sunny window or outside on a sunny day will be best., Make sure that there is nothing blocking the light from reaching the prism.
As the light passes through, it will bend and be split into a rainbow.
It might be easier to see if you aim the prism at a white wall or a white piece of paper. -
Step 3: Allow light to pass through the prism.
