Superposition
Karten in diesem Stapel (16)
- 1Principle of Superpositionwhen two waves of the same kind meet at a point in space, resultant displacement at the point is given by the vector sum of displacements due to each wave at that point
- 2Stationary wavesformed by superposition of two similar waves of exactly same amplitude, frequency & wavelength moving towards each other
- 3Waveform of stationary wave• wave profile does not propagate sideways
• oscillate with same f but different amp.
• within two cons. nodes every particle oscillates in phase
• distance b/w two adj. nodes is 1/2 wavelgth - 4Antinodepoint where amp. is max. (A)
- 5Nodepoint where amp. is zero (N)
- 6Progressive wavea
- 7Stationary waveb
- 8Diffractionbending of waves when travelling through aperture/pass round obstacle
- 9Coherent sourcesconstant phase difference
- 10Constructive Interferencetwo waves arrive in phase (phase diff. zero) to produce maximum
- 11Destructive Interferencetwo waves arrive in antiphase (pi rad) to obtain a minimum
- 12Conditions for observable Interference1. coherent sources/waves
2. approximate same amplitude
3. unpolarised waves / polarised in same place for transverse waves
4. interfere to give regions of maxima and minima - 13Conditions for CI and DI
- 14Young's Double Slit Experiment
- 15Diffraction grating
- 16Maximum order of bright fringes
