Step 2. Make a box for the prism

Make sure the box is closed on all sides except the top. On one side of the box, make a small rectangular hole. This hole should be cut in the bottom of the box and should be approximately 5mm wide.

Step 4. Turn off the lights in the room

It is difficult to see the light spectrum if the room is not dark enough. Try to cover any light source other than the one you are going to use.

Step 7. Observe the effects

A rainbow should immediately appear on the white paper. Using pastels of the same colors as the light prism effects, you portray the shapes in which the light presents itself in the best possible way.

Step 8. Discuss the observed effects with your peers

Ask questions like this:

  • What colors did the individual light bands form?
  • Were the colors arranged in a certain order? If so, indicate it.
  • Decide in class how you can best remember this color order.

Advice

  • If you have two prisms, cross their spectrum to see the effect that is created.
  • Make sure you are all gathered around the experiment "before" the room is darkened so you don't trip over.
  • If it's raining and the sun is shining through the clouds, turn your gaze to the sun and the sky. You will see a rainbow, because the light refracts when it passes through the rain, in the same way it does with the prism.
  • If you want to remember the order of colors, then use the formula: VIBVGAR

Violet, Indigo, Blue, Green, Yellow, Orange, Red.

Warnings

Do not look at the light directly, and even more so do not look directly at it sunlight.
