Properties of Waves Energy in Motion!!!

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

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.

299,292,458 m/s 343.2 m/s

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

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

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

Anatomy of a Wave Frequency? Wavelength? Rest Point?

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

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.
