  1. Wave Interactions Chapter 10 Section 3 Physics Standard 4f

  2. Reflection • Bouncing back of a wave when it meets a surface. • When wave medium are free (not attached), they will reflect the wave. • If wave medium is attached, it will turn wave upside-down and then reflect.

  3. Diffraction • Bending of waves as they pass an object’s edge or opening. • Original wave bent Diffraction

  4. Refraction • Bending of waves as they pass from one medium to another. • Ex: light traveling through water then air. • Light bent when enters water. Spoon appears to be cut

  5. Interference • Combo of 2 or more waves that exist in the same place at the same time. • Constructive interference: 2 waves combine so that resulting wave is bigger than the orig. waves Waves travel at same frequency

  6. Destructive Interference • 2 waves combine so that resulting wave is smaller than the largest of orig. waves. Waves travel at diff. frequencies

  7. Doppler Effect • Observed change in frequency of a wave when the source of the wave is moving. • Occurs in light and sound waves.
