Problem 6.59

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