Question

Compressions are the regions in which the ____ is ____.

  1. Pressure, low
  2. Pressure, high
  3. Density, low
  4. None of the above

hintHint:

Compressions are the regions in which the pressure and density are high

The correct answer is: Pressure, high


    • Compressions are regions of high pressure and high density.
    • The regions of low pressure and density create refraction
