  1. Wavelength Properties of Energy Comparing Wave Properties & Energy

  2. Essential Standard • 6.P.1Understand the properties of waves and the wavelike property of energy in earthquakes, light and sound waves.

  3. Clarifying Objective • 6.P .1.1 Compare the properties of waves to the wavelike property of energy in earthquakes, light and sound.

  4. Essential Question • How are Earthquake waves, Light waves, & Sound waves all alike?? • How are waves created? • What is light? • What is sound? • What is a Seismic Wave?

  5. Waves Transmit Energy • Waves transmit energy & not matter • Waves are simply a way for energy to go from one place to another (moving energy) • Think of a roller coaster: the energy is you in the coaster & the wave is the track that moves up & down

  6. Energy Vibrations • Energy causes materials to VIBRATE • These vibrations are carried on waves • These waves transmit/transfer energy from one place to another

  7. Essential Question • Get with a partner and answer… • How are waves created?

  8. Waves Travel through Matter • Almost all waves travel through some type of matter • Matter that waves have to travel is either a • Solid • Liquid • Gas • The only type of wave that does not have to travel through matter is an ELECTROMAGNETIC (light wave) WAVE which can travel through a vacuum

  9. Earthquake Energy • All an Earthquake is ENERGY moving through a solid • The energy of the Earthquake travels on a wave • Earthquake energy is called SIESMIC WAVES

  10. Earthquake Energy • Earthquakes use Longitudinal waves to move through the land (solid) • Sometime the energy of the Earthquake is so great that it splits the land in two

  11. Longitudinal Wave • Earthquake energy travels in Longitudinal waves through a solid • The energy moves on the wave because of compression & rarefaction repeating itself similar to a SLINKY

  12. Seismic Waves • http://www.youtube.com/watch?v=yOGoKCK17a4 • http://www.youtube.com/watch?v=QfmRf8iOBkI 0:00-1:08

  13. Essential Question • Get with a partner and answer… • What is a Seismic Wave?

  14. Sound Energy • Sound Energy also travels on a Longitudinal Wave • Sound Energy however can travel through all three types of matter • Solid • Liquid • Gas

  15. Sound Energy • Sound Energy begins to travel when there is some type of VIBRATION • This VIBRATION travels through either a solid, liquid or gas

  16. Sound Energy • Sound Energy bumps the vibration into PARTICLES (particles make up the solid, liquid, or gas) • The particles continue to bump into each other passing the sound energy on through a longitudinal wave

  17. Essential Question • Get with a partner and answer… • What is a Sound Wave?

  18. Light Energy • Light Waves (Electromagnetic Waves) are Transversal waves • They move energy up and down through space • Light Waves (Electromagnetic Waves) can but do not have to move through a medium

  19. Light Energy • Light waves (Electromagnetic Waves) are the only forms of energy that can travel through a vacuum • This means that light is the only form of energy that can travel through outer space is light energy which • It is important to remember that energy from the sun is light energy (Electromagnetic Energy) and must pass through a vacuum

  20. Essential Question • Get with a partner and answer… • What is light?

  21. Essential Question • Get with a partner and answer… • How are Earthquake waves, Light waves, & Sound waves all alike??

  22. EOG Questions • How are earthquakes, sound, and light waves alike? • A) They transmit energy. • B) They carry matter. • C) They travel in space. • D) They can be seen.

  23. Important Points • Energy causes materials to vibrate • The energy is carried on waves • Energy must travel through a medium in all instances except one (light energy) • Mediums include solids, liquids or gases • Earthquake energy has wavelike properties (Longitudinal) • Sound energy has wavelike properties (Longitudinal) • Light energy has wavelike properties (Transversal)
