Finding the distance between slits in double slit experiment

Click For Summary

Homework Help Overview

The discussion revolves around a problem related to the double slit experiment, specifically focusing on finding the distance between the slits. Participants are exploring the calculations and reasoning involved in deriving the necessary formula.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss their attempts to derive the formula needed to calculate the distance between the slits, with one member mentioning a sketch to aid in understanding. There are questions about the necessity of using a diagram versus applying a known formula directly.

Discussion Status

Some participants have confirmed their calculations, indicating a shared understanding of the numerical result. However, there is still exploration regarding the approach taken to arrive at that result, with no explicit consensus on the method being the most appropriate.

Contextual Notes

One participant expresses concern about the marks assigned to the question, suggesting that there may be expectations for a more detailed approach rather than simply applying a formula.

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

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
