In a double slit experiment having two slits of width 1.0 um spaced 4um apart, assume a beam of protons is incident on the slits after being accelerated from rest via a potential difference of around 2500V.
i) Determine the speed of the proton?
ii) Determine the wavelength of the proton?
iii) When the pattern of the detected protons is observed on the fluorescent screen 20m from the slits, determine the center-to-center spacing among the constructive interference maxima?
iv) Determine the full width of the central diffraction minimum?
v) Determine how many interference fringes will be observed within the central diffraction minimum?
