Chapter 18

1. What are light and sound forms of, and how do they move?

2. What do waves transfer? Please give examples.

3. Infer why a boat in the ocean only moves up and down as the waves pass but is not carried to shore by waves.

4. Explain what a periodic wave is and give an example.

5. In the space below, show an example of a wave.

6. define each word and give an example.

Wavelength:

Frequency:

7. Compare and contrast a transverse wave and a longitudinal (compressional) wave and give an example of each.

8. Identify at least one way in which scientists categorize waves.

9. What is the relationship between frequency and wavelength? What happens to the wavelength as the frequency increases?
