double slit experiment with electrons and larger particles

luckis11

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.

Joseph14

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 ?
