Transcribed Image Text:

A highly collimated (parallel) beam of electrons is shot through a single slit of width 12.0m. The electrons are moving with a speed of 5.01km/s. When they hit the screen, located at distance 1.74m away, the distribution of hitting positions makes an interference pattern with a central peak and minima on either side. Part a This pattern will be identical to the pattern produced by light of what wavelength? What is the width of the central peak (equivalently, distance between the minima on either side)? Assume the small-angle assumption holds. A highly collimated (parallel) beam of electrons is shot through a single slit of width 12.0m. The electrons are moving with a speed of 5.01km/s.
