  1. Using the Internet and/or your textbook: Look up THE DOPPLER EFFECT: 1. The DOPPLER EFFECT and SOUND 2. The DOPPLER EFFECT and LIGHT (redshift and blueshift) • Set up a chart with the following information: • In your own words, define the terms (1 and 2) • Include a visual for each term • Include a real-life example for each term • *choose a source that is reliable (scientific), yet simple to understand. Document your sources.

  2. TYPES OF WAVES Chapter 15, Section 1, pp 505-513

  3. I. What is a wave? • a traveling ______________ that carries _________ from one place to another. • 0o0o0o baby I love your wave... DISTURBANCE ENERGY Ex: _________________________________ Ocean, microwaves, sound, light, radio…

  4. Moves ________… not _______ *matter and objects “bob up and down” as the wave passes by… ENERGY MATTER

  5. Tsunamis travel outward in all directions

  6. The matter through which a wave travels is called a ________ (pl = ______) MEDIUM MEDIA • All phases of matter (______, ______, ____) may allow waves to travel through them. SOLIDLIQUIDGAS SOLID LIQUID GAS

  7. VIBRATIONS • Waves are caused by ____________ • Ex: _______________________________ • _________________________________ Wave tanks, vocal cords, guitar strings, earthquakes, electrons, lips (trumpet)

  8. Types of Waves MECHANICAL • _____________ waves: • Waves that need a _________ to travel • Examples: • _______________________________ MEDIUM Slinky, water, earthquakes, SOUND

  9. SOUND = MECHANICAL WAVE NO SOUND IN SPACE!

  10. ELECTROMAGNETIC • ___________________ Waves: • Waves that do not require a ________ to travel • Pitbull & EMS?! • Examples: see next slide MEDIUM

  11. ELECTROMAGNETIC WAVES Low frequency; Long Wavelength High frequency; Short Wavelength

  12. ELECTROMAGNETIC WAVES

  13. TYPES OF WAVES MEDIUM WAVE • Waves are also classified by comparing the motion of the _________ to the motion of the ______. …SLINKY DEMO!!

  14. TRANSVERSE ______________ WAVES • Motion of the _________ is at • a ______ angle to the direction of the wave. MEDIUM RIGHT

  15. EXAMPLES OF TRANSVERSE WAVES 1. ELECTROMAGNETIC WAVES

  16. 2. SHEAR (S) WAVES OF EARTHQUAKES

  17. LONGITUDINAL ______________ WAVES MEDIUM PARALLEL SAME • Motion of the _________ is _________ ( _____ direction) to wave direction • Surfs Up Dude Song!

  18. Made of a series of ________________ • (“crowded” areas) and ______________ • (“less crowded” areas). COMPRESSIONS RAREFACTIONS

  19. Compressions and rarefactions

  20. EXAMPLES OF LONGITUDINAL WAVES Sound is a VIBE! 1. SOUND WAVES

  21. 2. PRIMARY (P) WAVES OF EARTHQUAKES

  22. SURFACE __________ WAVES • motion of the medium is perpendicular and parallel to the energy to produce an overall __________ motion CIRCULAR • occur at the boundary of two different media

  23. THE NATURE OF WAVES…
