  1. 1. Waves
  2. 2. <ul><li>What are waves? </li></ul><ul><li>Used to transfer energy </li></ul><ul><li>Waves travel through different mediums </li></ul><ul><li>- solid </li></ul><ul><li>- liquid </li></ul><ul><li>- gas </li></ul>
  3. 3. <ul><li>Parts of a </li></ul><ul><li>wave </li></ul>
  4. 4. <ul><li>Categories of waves </li></ul><ul><li>Wave speed </li></ul><ul><li>Wavelength </li></ul><ul><li>Frequency </li></ul><ul><li>Transverse </li></ul><ul><li>Longitudinal (compression) </li></ul><ul><li>How fast a wave moves </li></ul><ul><li>Distance between waves </li></ul><ul><li># of waves in a given period of time </li></ul>Think Slinky!!
  5. 5. <ul><li>Properties </li></ul><ul><li>of waves </li></ul><ul><li>a. </li></ul><ul><li>b. </li></ul><ul><li>As frequency decreases the wavelength increases </li></ul><ul><li>As frequency increases the wavelength decreases </li></ul><ul><li>The higher the frequency the more dangerous the wave. </li></ul>
  6. 6. <ul><li>Sound </li></ul><ul><li>Is a compression wave </li></ul><ul><li>requires molecules to vibrate off of. If no molecules then no sound. </li></ul><ul><ul><li>Would you hear a boom box in outer space? </li></ul></ul><ul><li>Amplitude = Loudness </li></ul><ul><ul><li>Increase the amplitude the louder the sound </li></ul></ul><ul><li>Frequency & Pitch </li></ul><ul><ul><li>The higher the frequency the higher the pitch </li></ul></ul>
  7. 7. <ul><li>Behavior </li></ul><ul><li>of waves </li></ul><ul><li>Reflection: when a wave bounces off an object </li></ul><ul><ul><li>Echo is a reflected sound wave </li></ul></ul>
  8. 8. <ul><li>Behavior </li></ul><ul><li>of waves </li></ul><ul><li>Refraction: is when the wave bends because it changes mediums. </li></ul><ul><ul><li>This is why a pencil looks broken when put into a glass of water. </li></ul></ul>
  9. 9. <ul><li>Behavior </li></ul><ul><li>of waves </li></ul><ul><li>Diffraction: When an object causes a wave to change or bend around it. </li></ul>
