Superposition
Cards in this deck (7)
- 1What is the principle of superposition?When two or more waves of the same type meet at a point, the resultant displacement of the oscillations will be the vector sum of the individual displacements.
- 2When will constructive interference occur?If both waves have the same sign (positive or negative) displacement
- 3When will destructive interference occur?At the point of overlap, if one wave has a positive displacement and the other has a negative displacement
- 4Constructive and destructive interference can be for both.....Progressive and standing waves
- 5If we superpose two of the same wave, what happens?The amplitude of the new wave is double the original(s)
This is constructive interference - 6If we superpose two waves in anti-phase (180 degrees out of phase) we get.....A flat-line
This is destructive interference - 7Superposition diagrams:
