Abeam of electrons is accelerated from rest through a potential difference of 0.200 kv and then passes through a thin slit. when viewed far from the slit, the diffracted beam shows its first diffraction minima at ± 12.1 ∘ from the original direction of the beam when viewed far from the slit. do we need to use relativity formulas? explain wide is the slit?
