  1. ...由那個single slit繞射(diffraction)出來的光。 而要看到一個穩定的(stable)相干現象( interference pattern),首要條件是兩個波(wave)要有穩定的相位差。 如果不加single slit,那麼...

  2. ...spread out. In that case, light from the two slits would not be met and interference could not take place. As you should have learnt that in a single slit diffraction...

  3. ...m = 5 m The signal is minimum when destructive interference occurs, i.e path difference = (m + 1/2)入 where m...clear from the calculation that between two sucessive destructive interference , there is a shift of one wavelength .... 2012-01-25 11...

  4. ...the light in the film. Also, I guess you are talking the interference of reflected light. Normally, we always consider reflected light...

  5. 1. I suppose you mean forming a stable interference pattern, as interference always takes place when two...much smaller than the slit separation in double slit interference . This leads to the no. of fringes...

  6. interference 唔一定係 coherent waves 先會發生. Interference 是WAVE 的特性. 任何WAVE 都能夠產生 interference . 包括electromagnetic wave. 即光. destructive interference occurs when two waves...

  7. ...than the width of slits in the double-slit arrangement. This will give an interference pattern with varying fring separation and intensity (your diagram 1). ...

  8. Applet shows interference of waves from two point sources. The white circles can...trough combining. The red line passes through points where interference is destructive. On this line crest and trough combine. You can...

  9. I presume that you refer to Young's double slit interference . In the experiment, the separation of the two slits could not be too large...

  10. Retroactive interference (RI) is introduced from interference theory which categorises...
