Flashcards
Combining Waves
Cards in this deck (20)
- 1SuperpositionWhen 2 waves of the same type overlap and interact
- 2Overall Displacement =Vector Sum of the 2 wave displacements
- 3InterferenceSuperposition of waves from 2 coherent sources of wave leading to a fixed pattern
- 4To have interference the waves must....have a fixed phase difference and same frequency
- 5n x wavelengthsn = integer = constructive
n= not integer = destructive - 6A Stationary Wave is formed by ...the superposition of 2 progressive waves of the same frequency and amplitude travelling in opposite directions
- 7When waves are reflected off a rigid boundary.....the reflected wave has a 180 degree shift
- 8NodeZero Amplitude
- 9Anti NodeMax Amplitude
- 10HarmonicsMore Anti nodes
Higher Frequency - 11f=v/wavelength
- 12forming of first harmonic1 Tension

2L mass/L - 13Youngs Double SlitsDemonstrates Interference between coherent light sources
- 14Dark FringeDestructive
- 15Light FringeConstructive
- 16Light from 2 sources travel different paths....leading to a phase difference
- 17Condition for Constructive InterferenceDistance Between Slits x sin(beam to screen) = integer x wavelength
- 18To predict fringe spacingWavelength x distance slits to screen
------------------------------------------
distance of slit to slit - 19Happens in ....out room using bright light or laserblacked
- 20Lasers are....precise
polarised
coherent
produces stationary wave
source of intense single wavelength light
