Double slit experiment with electrons and larger particles

Click For Summary

Discussion Overview

The discussion revolves around the double slit experiment, specifically focusing on the wavelength of electrons and larger particles like C60. Participants explore the relationship between wavelength, momentum, and experimental conditions without reaching a consensus on the specific values or methods for determining wavelength in these contexts.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests the wavelength derived from the interference patterns in the double slit experiment for electrons and larger particles, indicating a lack of specific data.
  • Another participant states that the wavelength is related to the momentum of the particle, providing the equation λ = h/p.
  • A participant emphasizes the need for specific data to calculate wavelength, suggesting that without it, the question lacks meaning.
  • There is a mention of the equation n*λ = d*sin(θ) in relation to the experiment.
  • Participants discuss the implications of velocity on the wavelength of electrons and larger particles.
  • One participant inquires about the environmental conditions necessary for conducting the double slit experiment with C60, suggesting the use of a liquid medium.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific wavelength for electrons and larger particles, with multiple competing views on how to derive or calculate it based on available data and conditions.

Contextual Notes

The discussion highlights limitations related to the lack of specific data and assumptions about the experimental setup, which affect the ability to derive meaningful conclusions regarding wavelength.

The where the interference tassles appear on the film at the double slit experiment, made the conclusion that the waveleghth λ of the wave of the red right is λ=(that much). For the blue light, λ=(that much), and so on. But I cannot find the λ=(that much) for the experiment with electrons and larger particles. Where is it? A link please?

The wavelength depends on the momentum of the particle:

\lambda = \frac{h}{p}
 
I am asking the λ which is derived by the interference tossles by the method of Thomas Young alone. No uncertainty, E=hf and all such stuff.
 
n*\lambda=d*sin(\theta)

Why are you giving me equations? I don't have any data to use any equation anyway.
 
that depends on the velocity (momentum) of the electron, C60, or what ever large particle you are using. If you don't have any specific velocity or data the question is meaningless.
 
The same goes for the width of each slit?
 
what kind of environment will you use in double-slit experiment with C60 ? somekind of liquid ?
