Finding the distance between slits in double slit experiment

Click For Summary
SUMMARY

The forum discussion centers on calculating the distance between slits in the double slit experiment, specifically deriving the variable 'd'. The user successfully computed 'd' as 2.92 x 10-4 m

and sought confirmation on their approach. The conversation highlights the importance of understanding the underlying principles of the double slit experiment rather than relying solely on established formulas.

PREREQUISITES
  • Understanding of wave-particle duality in quantum mechanics
  • Familiarity with the double slit experiment setup
  • Basic knowledge of trigonometry and geometry
  • Ability to interpret and create scientific diagrams
NEXT STEPS
  • Research the mathematical derivation of the double slit interference pattern
  • Learn about the impact of slit width and distance on interference patterns
  • Explore the concept of fringe spacing in relation to slit separation
  • Investigate advanced topics in quantum mechanics related to wave functions
USEFUL FOR

Students studying physics, educators teaching quantum mechanics, and anyone interested in experimental physics and wave phenomena.

Hi so I have been struggling on a part of a question that I'm not too sure on how to solve
For some reason PF is not allowing me to pose an image of the question on here so I have provided a link to it

Question link:

And here is what I tried to do so far, I drew a sketch of a diagram to help me derive the formula that I need

Sketch:
Working out:

I got little d to be 2.92 x 10-4m

Any help would be really appreciated! Thanks

I computed it also, and got the same answer.

Sure. What is your problem ?

Sorry I just got threw off here as it was set to be 12 marks, so I though I had to make use of a diagram or something to get to an equation I can use to find d. And not just dive straight into a known general formula to calculate d, as it would seem to be too much little work.

Looks about right now then I guess
