Question

One of the most compelling demonstrations of wave-particle duality is the wave-like interference pattern displayed by electrons (which otherwise behave like a particle) when passing through a pair of double slits. If a beam of electrons is created by accelerating them from rest through a potential difference of just 500V, and this beam is trained on a pair of slits 10mircometers apart with a detector 1 m behind the slits, what is the seperation between adjacent bright spots on the screen? The answer is 5.47 micrometers, but how do you get it.

Explanation / Answer

= x d /L

= h x c / 1.6 x 10^-16 x 500

now

d = h x c x 1 /  1.6 x 10^-16 x 500 x 10 x 10^-6 = 5.47 micro m
