Superposition
Superposition
Waves pass through, displacements combine, continue unchanged
Superposition mathematical rule
Superposition mathematical rule
Add displacement from wave 1 to displacement from wave 2
Constructive interference occurs when
Constructive interference occurs when
Crests align with crests, troughs align with troughs
Result of 2 identical waves in phase
Result of 2 identical waves in phase
Twice the amplitude of either original wave
Destructive interference occurs when
Destructive interference occurs when
Crest coincides with trough from another wave
Result when identical waves meet out of phase
Result when identical waves meet out of phase
Displacements cancel completely, zero displacement
