1. Properties of Waves Energy in Motion!!!

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

3. Transverse Wave Transverse waves move up and down in the direction of the wave. Transverse waves move up and down in the direction of the wave. Transverse waves are LIGHT waves. Transverse waves are LIGHT waves.

4. Compressional Wave Compressional waves are sound waves and seismic waves. Compressional waves are sound waves and seismic waves. Yelling and Earthquakes…?

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

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