Superposition
Flashcards do conjunto (7)
- 1Principle of superpositionWhen 2 or more waves overlap, the resultant displacement at any instant is the vector sum of the individual displacements that each wave could cause at that point
- 2InterferencePhenomenon where 2 or more wavestrains overlap to produce regions of constructive and destructive summation according to the principle of superposition
- 3Coherent waveConstant phase difference
Same wavelength and frequency
Polarised in the same plane
Overlapping waves - 4Stationary wavesWhen 2 identical waves travelling in opposite directions towards each other superpose, resulting in regions of maxima (antinodes) and minima (nodes)
- 5DiffractionPhenomenon where a wave spreads out after passing through a narrow aperture or round an obstacle
(significant when size of aperture = order of magnitude of wavelength of wave) - 62 source interference conditionsWaves must overlap
Sources must be coherent
Waves approximately same amplitude
Transverse waves must be unpolarised/polarised in same plane - 7—
