Problem 6.59

A parallel stream of electrons accelerated by a potential difference \(V=25\) V falls normally on a diaphragm with two narrow slits separated by a distance \(d=50 \mu \mathrm{m} .\) Calculate the distance between neighbouring maxima of the diffraction pattern on a screen located at a distance \(l=100 \mathrm{~cm}\) from the slits.

Reveal Answer
Δx=2πl/d2meV=4.9μm\Delta x=2 \pi \hbar l / d \sqrt{2 m e V}=4.9 \mu \mathrm{m}
