Wavelength Properties of Energy Comparing Wave Properties & Energy

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

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

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?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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)
