- An electron microscope uses electrons accelerated by a voltage of \( 50 \mathrm{kV} \). Determine the de-Broglie wavelength associated with the electrons.
(a) \( 2.5 \times 10^{-12} \mathrm{~m} \)
(b) \( 1.5 \times 10^{-12} \mathrm{~m} \)
(c) \( 5.5 \times 10^{-12} \mathrm{~m} \)
(d) \( 0 \mathrm{~m} \)
