Through what potential difference ΔV
must electrons be accelerated (from rest) so that they will have the same wavelength as an x-ray of wavelength 0.155 nm
?
Use 6.626×10−34 J⋅s
for Planck's constant, 9.109×10−31 kg
for the mass of an electron, and 1.602×10−19 C
for the charge on an electron. Express your answer using three significant figures.
