Double slit experiment with electrons and larger particles

In summary, the conversation discusses the interference tassels appearing on film at the double slit experiment, which led to the conclusion that the wavelength of red light is λ=(that much), and for blue light, λ=(that much). However, the conversation moves on to discuss the wavelength for the experiment with electrons and larger particles, which is dependent on the momentum of the particle according to the equation \lambda = \frac{h}{p}. The speaker is looking for the λ derived from the interference tassels method of Thomas Young. They mention the uncertainty principle and the equation E=hf, but state that they do not have any data to use equations. The wavelength also depends on the velocity (momentum) of the particle being used

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:

[tex]\lambda = \frac{h}{p}[/tex]

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.

[tex]n*\lambda=d*sin(\theta)[/tex]

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 ?

1. What is the double slit experiment with electrons and larger particles?

The double slit experiment is a famous physics experiment that demonstrates the wave-particle duality of matter. It involves shooting individual particles, such as electrons or larger particles, through two parallel slits onto a screen and observing the resulting interference pattern.

2. How does the double slit experiment work?

The experiment involves a beam of particles, such as electrons, being directed towards a barrier with two parallel slits. The particles pass through the slits and create an interference pattern on a screen behind the barrier. This pattern is created because the particles behave like waves and interfere with each other as they pass through the slits.

3. Why is the double slit experiment significant?

The double slit experiment is significant because it provides evidence for the wave-particle duality of matter. It shows that particles, such as electrons, can behave like waves and exhibit interference patterns, which was previously thought to only occur with waves. This has important implications for our understanding of the fundamental nature of matter.

4. How does the double slit experiment with electrons differ from that with larger particles?

The double slit experiment with electrons and larger particles is essentially the same in terms of the principles involved. The main difference is that electrons have a smaller mass and wavelength compared to larger particles, such as atoms or molecules. This means that the interference pattern observed with electrons will be more pronounced and easier to observe.

5. What are the practical applications of the double slit experiment?

The practical applications of the double slit experiment are wide-ranging and include fields such as quantum mechanics, optics, and information technology. It has also been used to study the behavior of particles in various physical systems and has implications for the development of new technologies, such as quantum computing.
