Watch the following video about the different types of light waves on the electromagnetic spectrum:

After you have reviewed the resources above see if you can answer the following questions.Give them a try as you prepare for the test this week!

1. Relate sunlight to the electromagnetic spectrum. Where do the waves that are commonly called light fall on the spectrum?
2. Define infrared light. How can infrared light be detected?
3. What is visible light? What determines the color of visible light?
4. Describe ultraviolet light. How and why should you protect your skin from ultraviolet light?
5. What is reflection? What happens if waves strike a reflective surface at an angle other than 90 °?
6. Define refraction. Why does refraction occur?
7. When does diffraction occur? How is wavelength related to diffraction?
