What is width of central maximum of the diffraction pattern

Reference no: EM13666058

A mono energetic beam of electrons (me = 9.11 x 10^-31 kg) whose kinetic energy is 120 eV is incident on a single slit of width 1.0 nm. A diffraction pattern is formed on a screen 20 cm from the slit. What is the width of the central maximum (i.e. the distance among first minima) of the diffraction pattern?
