  1. Vocab Wave Length λ=lambda

  2. Vocab amplitude A Amplitude Distance from rest position

  3. Vocab Period • Time it takes for one complete wave to pass by T = period

  4. Vocab Frequency How many waves pass in 1 second Measured in Hz = s-1

  5. Vocab Longitudinal Waves Medium vibrates in the same direction as the direction energy moves Compression waves Sound

  6. Vocab Transverse Waves • Medium (substance) vibrates 90° to the direction energy moves Perpendicular Light

  7. Vocab node Standing Waves anti-node Modes Tones Guitar strings 2 waves with equal f and λthat perfectly reinforce each other.

  8. Vocab Overtones Overtone frequencies are the higher modes of vibration and make each instrument sound unique 2nd mode = 1st harmonic overtone.

  9. Vocab Harmonics Specific overtone frequencies that create standing waves. The length of the string and velocity of the wave determine the frequency

  10. Vocab Timbre Sound quality, lets you hear the difference between 2 instruments playing the same note Tam-brr Special sounds depth
