The simulations we did with electrons seem to imply that wave behavior is associated with electrons. As electron energy increases the distance between dark regions in the interference pattern decreases. If we compare this to our observations of light we could say that as the electron energy increases the electron wavelength decreases.
Let us now examine some other small particles and see if they exhibit wave behavior.
Proton - positively charged particle that has a mass approximately 2000 times that of an electron Neutron - neutral (no charge) particle that has a mass approximately 2000 times that of an electron Pion - positively charged particle that has a mass approximately 300 times that of an electron
We will use these particles as sources in a double slit experiment to investigate possible wave behavior.
