In an earlier version of the double-slit experiment, scientists used helium atoms (from a reservior kept at 295 K) that exit the nozzle after expansion with a wavelength λ = 0.56 Å. The spacing d between the slits is 8 ± 0.6 µm, and the distance between the slits and the detection plane is 0.64 m in their experiement.
Calculate the spacing between maxima in the detection plane. The observed spacing is 4.5 ± 0.6 µm.
A highly collimated (parallel) beam of electrons is shot through a single slit of width 17.5μm. The electrons are moving with a speed of 7.357.35km/s. When they hit the screen, located at distance 1.57m away, the distribution of hitting positions makes a pattern with a central peak and minima on either side. What is the width of the central peak (equivalently, distance between the minima on either side)?
