  1. Magic Letter, Magic Word Vocabulary review

  2. Magic Letter N • Point of zero amplitude on a standing wave • Has no pleasing patterns

  3. Magic Letter A • Maximum distance a transverse wave travels from rest position • Maximum amplitude on a standing wave

  4. Magic Letter F • Number of complete waves that pass a given point in a certain amount of time

  5. Magic Letter W • Disturbance that transfers energy from place to place • Distance between two corresponding parts of a wave

  6. Magic Letter M • Material through which a wave travels • Waves that require a medium to travel • Set of notes combined a pleasing pattern

  7. Magic Letter T • Waves that move medium at right angles to direction of wave’s motion • Low point on a transverse wave

  8. Magic Letter L • Waves that move medium parallel to direction of wave’s motion • Perception of energy of a sound • As the energy of a sound increases, the ____________ also increases

  9. Magic Letter C • When the particles of medium are close together in a longitudinal wave • High point of a transverse wave • Type of interaction where two waves meet and produce a higher amplitude

  10. Magic Letter R • When particles of a medium are spread out in a longitudinal wave • When an object or wave hits a surface it can’t pass and bounces back • Bending of waves due to a change in speed • Occurs when one object causes a nearby object to vibrate at a natural frequency

  11. Magic Letter U • Frequencies that are above the normal human range

  12. Magic Letter E • Reflected sound wave • Waves that do not require a medium to travel • Ability of a medium to bounce back after being disturbed

  13. Magic Letter S • How far a wave travels in a given length of time • Disturbance that travels through a medium as a longitudinal wave • Produced if the incoming wave and reflected wave have just the right frequency.

  14. Magic Letter D • Unit used to compare loudness of sounds • When a wave moves around a barrier or through an opening in a barrier, it bends and spreads out • Type of interaction that occurs when two waves meet and create a smaller amplitude • The reason why a siren sounds differently as it moves towards you and then as it passes you.

  15. Magic Letter I • The following are types of ____________ • Reflection, refraction, diffraction, standing wave, interference • When two waves meet • Frequencies below the normal human range • Amount of energy a sound wave carries per second through a unit area

  16. Magic Letter P • The following are ___________ of waves • Amplitude, frequency, wavelength, and speed • How high or low a sounds seems

  17. Magic Letter H • Patterns of standing waves
