1. Properties of Waves
Energy in Motion!!!

2. Waves Waves are ENERGY in Motion. There are two types of waves—
Type 1—Transverse Wave
Type 2—Compressional or longitudinal Wave

3. Parts of a Wave Crest-peak/top of a wave (mtn.)
Trough-bottom of a wave (pigs)
Wavelength-distance from crest to crest or trough to trough
Amplitude-distance from rest to crest
Rest Point-where the wave crosses the center point.
Frequency-number of wavelengths passing in 1s.

4. 299,292,458 m/s m/s

5. Transverse Wave
Transverse waves move up and down in the direction of the wave.
Transverse waves are LIGHT waves that move through empty space.

6. Compressional Wave
Compressional waves are sound waves and seismic waves that require a medium to move.
Yelling and
Earthquakes?

7. Sound travels faster through water vapor, liquid water, or ice? Why?

8. Anatomy of a Wave
Frequency? Wavelength? Rest Point?

9. Review… What are waves? What are the two types of waves?
Example of each wave type?
Parts of a wave?

10. Exit Ticket
Why is a sound wave with larger amplitude more likely to damage your hearing than a wave with a small amplitude?
Does thunder or lightning occur first? Explain.
