LO4- Sound Waves

  1. 1. Relationship between displacement and pressure Q:When is pressure variation the greatest? a) It is constant b) When displacement is a minimum c) When displacement is at a maximum d) When displacement is through zero
  2. 2. Relationship between displacement and pressure Q:When is pressure variation the greatest? a) It is constant b) When displacement is a minimum c) When displacement is at a maximum d) When displacement is through zero
  3. 3. Relationship between displacement and pressure Q: When is pressure variation the greatest? a) It is constant- cannot be constant because as the particles are displaced there are pressure variations in medium. b) When displacement is a minimum- opposite functions c) When displacement is at a maximum- this would mean they are in phase which they are not d) When displacement is through zero- this is true because a region of high pressure has particles pushed into it from both sides. On the left it is positive and on the right it is negative. Therefor the displacement must go through zero.
