Sound Model

What is the number image showing?

• Crest

  (top of the wave)

• Trough

  (bottom of the wave)

• Wavelength

  (length of a wave that impacts the frequency and pitch)

• Amplitude

  (volume of the wave shown as displacement or height above the dotted resting point)

What is different about sound wave A and B?

• Different AMPLITUDE (volume) shown by displacement (how high the wave goes)

• Different PITCH shown by wavelength differences and frequency (number of waves)
