Chapter 11 Vocab 9th Grade--Waves and Their Parts

  1. 1. Vocab Chapter 11—Waves
  2. 2. • The greatest distance that particles in a medium move from their normal position when a wave passes Amplitude
  3. 3. • Any interference in which waves combine so the resulting wave is bigger than the original wave Constructive Interference
  4. 4. • The highest point of a transverse wave Crest
  5. 5. • Wave caused by a disturbance in electric and magnetic fields—DOES NOT require a medium (Ex: Light) Electromagnetic Waves
  6. 6. • Any interference in which waves combine so the resulting wave is smaller than the largest of the original waves Destructive Interference
  7. 7. • The bending of a wave as it passes an edge/opening Diffraction
  8. 8. • An observed change in the frequency of a wave when the source or observer is moving Doppler Effect
  9. 9. • The number of vibrations that occur in a 1 second time interval Frequency
  10. 10. • The combination of 2+ waves that exist in the same place at the same time Interference
  11. 11. • Wave that causes the particles of the medium to vibrate parallel to the wave’s direction. Longitudinal Wave
  12. 12. • The matter through which a wave travels Medium
  13. 13. • Waves that require a medium Mechanical Wave
  14. 14. • The time required for one full wavelength to pass a certain point Period
  15. 15. • The bouncing back of a wave as it meets a surface/boundary Reflection
  16. 16. • The bending of a wave as it passes from one medium to the other. Refraction
  17. 17. • Wave form caused by interference that appears not to move along the medium that shows some regions of no vibration (nodes) and other regions of maximum vibrations (antinodes) Standing Wave
  18. 18. • Wave that causes the particles of the medium to vibrate perpendicular to the direction the wave travels. Transverse Wave
  19. 19. • The lowest part of a transverse wave Trough
  20. 20. • A disturbance that carries energy through matter and space Wave
  21. 21. • The distance between ant 2 successive identical parts of a wave. Wavelength
  22. 22. • The speed at which a wave passes through a medium Wave Speed
