ExperimentLight and the Color Spectrum (Part 3)
What You'll Learn
Light behaves as both a wave and a particle. White light can be separated into a spectrum of colors using a prism. Each color has a different wavelength.
Key Words
- model
- prototype
- design
Materials Needed
- scissors
- straws
- paper clips
- rubber bands
Safety First
- Work in a well-ventilated area when using vinegar or other strong-smelling substances.
- Dispose of materials properly after the experiment.
- Handle glass items carefully to avoid breakage.
