A single beam of electrons shines on a single slit of width 3.3nm. A diffraction pattern (of electrons!) is formed on a screen that is 2.1m away from the slit. The distance between the central bright spot and the first minimum is 2.1cm.What is the speed (m/s) of the electrons?Make use of the small angle approximation.
A single beam of electrons shines on a single slit of width 9.5nm. A diffraction pattern (of electrons!) is formed on a screen that is 7.6m away from the slit. The distance between the central bright spot and the first minimum is 1.9cm.What is the wavelength (nm) of the electrons?Make use of the small angle approximation
A single beam of electrons shines on a single slit of width 8.7nm. A diffraction pattern (of electrons!) is formed on a screen that is 3.9m away from the slit. The distance between the central bright spot and the first minimum is 5.7cm.What is the kinetic energy (keV, i.e. kilo electron-Volts) of the electrons?Make use of the small angle approximation.
