Slit for the Double Slit Experiment

Click For Summary

Discussion Overview

The discussion revolves around sourcing slits for conducting the Double Slit Experiment, including methods for creating slits and purchasing options. The scope includes practical applications and experimental setups.

Discussion Character

  • Exploratory, Experimental/applied

Main Points Raised

  • One participant inquires about where to obtain a slit for the Double Slit Experiment.
  • Another participant suggests using the eye of a needle or pencil leads for crude single slits and proposes cutting slits in an opaque sheet with a straightedge and Xacto knife for more precision.
  • A different participant mentions that using black cardboard to cut slits could work well with a laser, emphasizing the need for the slits to be close enough to be illuminated.
  • One participant provides a commercial option, mentioning that Edmund's sells a diffraction and interference kit, suggesting that it may be possible to obtain just a double-slit slide by contacting them.

Areas of Agreement / Disagreement

Participants present various methods for obtaining or creating slits, but there is no consensus on a single best approach or source.

Contextual Notes

Some suggestions depend on the type of light source used, and there may be limitations regarding the precision and applicability of homemade slits versus commercially available options.

I was wondering where could I get a slit for the Double Slit Exeriment that
I am trying to do.Thanks

I have heard that you can make one using the eye of a needle or pencil leads. Rather crude and only really useful for single slits. You could also just make one, you could take an opaque sheet of material and using a straightedge and Xacto knife carefully cut the slits.

First you need to choose what your source will be for the experiment. If it is a laser you could just probably use black cardboard that you cut the slits in very carefully. Just make sure that the slits are close enough to be both be illuminated by the laser. For lower frequencies, you will need to use a conductor as your material.
 


Thanks guys
