Presentation Transcript

1. Types of Waves and Energy Types of waves Energy Transport

2. Types of waves http://www.walter-fendt.de/ph11e/stlwaves.htm http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=14.0 Transverse: Wave moves medium moves Demo Applet Longitudinal: Wave moves medium moves Demo Applet Demo

3. Demo the human wave

4. Types of waves Sound is longitudinal: Demo - speaker and battery

5. Types of waves Sound is longitudinal:

6. Types of waves Surface Wave: Longitudinal and transverse Tsunami - longitudinal wave

7. Types of waves Electromagnetic Waves - Transverse waves Require no medium - can travel through vacuum Travel at 3.00 x 108 m/s in a vacuum (else slower) Speed is independent of speed of source/observer Radio, microwave, Infrared, Light, UV, XRay, Gamma Rays are all EM waves. (Cheer)

8. Types of waves Mechanical (requiring a medium) Electromagnetic (need no medium) S (Shear) Earthquake waves Waves in guitar strings Surface waves on water All EM Waves: Radio, Microwave, IR, Light, UV, X- Ray, Gamma rays Transverse P (Pressure) Earthquake waves Sound waves Compression waves in a spring Surface waves on water Longitudinal

9. Types of waves Longitudinal waves can pass through fluids, Transverse cannot. Only P earthquake waves can pass straight through the earth: S wave The core of the earth is liquid (Earth is like an egg) P wave

10. Energy Transport Waves transport energy: Sun to earth Sound to microphone Earthquakes Microwaves Ocean waves Demo - speaker, concentrator
