  2. What are Waves? • A wave is a repeating disturbance or movement that transfers energy through matter or space. • Ocean waves disturb the water and transfer energy through it. • During earthquakes, energy is transferred in powerful waves that travel through the earth. • Light also is a type of wave that can travel through empty space to transfer energy from place to place, just like when the Sun sends energy to Earth.

  3. Transverse Waves • The matter in the medium moves back and forth at a right angle to the direction the wave is traveling. • Transverse waves only travel through matter. • To show an example of a transverse wave you could shake one end of a rope while someone else holds the other end, the energy from your hand will create a wave.

  5. Compressional Waves • Matter in the medium moves back and forth along the same direction the wave travels. • Like a transverse wave, a compressional wave only travels through matter. • One way to model a compressional wave is to use a slinky and squeeze several coils together, let go of the coils, and watch a wave travel through the spring.

  7. Seismic Waves • Seismic waves are created from earthquakes. • Seismic waves are a combination of transverse and compressional waves. • They travel through Earth and along Earth’s surface. • When objects absorb energy from a seismic wave the object will move or shake. • The more of Earth’s crust that is moved the more energy there is released.

  9. Section 1 Vocabulary Wave- repeating disturbance or movement that transfers energy through matter or space. Medium- the matter that waves travel through Transverse Wave- matter in the medium moves back and forth at right angles to the direction that the wave travels. Compressional Wave- matter in the medium moves back and forth along the same direction that the wave travels.
