When white light passes through things such as water and prisms, the light rays are refracted or bent into the various colors of the spectrum. These colors always appear in the same order. Do you know the order of these colors? Drag your mouse over the different light rays to reveal the order of spectrum colors. A great way to remember the colors of the spectrum is to remember ROY G. BIV - see if you can tell what it stands for.
Materials:
- Flashlight
- Prism
- Prepared clear gelatin
- Clear cup
- Water
- Dark room
- Light colored backdrop
- Various clear liquids
Conclusions:
- Which materials did you find best worked to reflect light?
- Did the angle of light make a difference?
