Presentation Transcript

  1. Waves

  2. Waves • Waves- Rhythmic disturbances that carry energy without carrying matter • Molecules bump each other and pass energy from molecule to molecule

  3. Mechanical Waves • Mechanical Waves- Types of waves that use matter to transfer energy. • Matter is called a medium • Ex: Water is a medium for ripples on a pond • Sound waves cannot travel in outer space because there isn’t any air

  4. Transverse Waves • Transverse Waves- Wave energy causes the matter in the medium to move up and down or back and forth at right angles to the direction the wave travels • Crests- High points in the wave • Troughs- Low points in the wave

  5. Compression Waves • Compression Wave- Matter in the medium moves forward and backward along the same direction that the wave travels • Ex: Sound Waves • All waves are produced by something vibrating

  6. Sound Waves • Sound waves are created when a surface… • Moves upward and creates a compression- molecules are pushed close together • Moves downward and creates a rarefaction- molecules that are farther apart

  7. Electromagnetic Waves • Electromagnetic Waves- Waves that travel through space where there is no matter • Ex: radio waves, infrared, light (visible), U.V. (Ultraviolet), X-rays, and gamma rays • Radiant energy is from the sun • 92% are infrared and visible light…small amount is ultraviolet

  8. Wave Project • Include- Wave Type (Mechanical or Electromagnetic) • Include- Motion (Transverse or Compression) • Include- Examples of where you might see your wave. • Include- Pictures
