question 12

Multiple Choice

An electron microscope operates with electrons of kinetic energy 100 keV. What is the wavelength of these electrons? Assume this speed is not relativistic. (h = 6.63 *10 ^{- 34} J.s, c = 3.00 * 10⁸ m/s, 1 eV = 1.60 *10 ^{- 19} J, and m_e = 9.11 *10 ^{- 31} kg)

• A) 5.49 *10 ^{- 12} m
• B) 7.14 *10 ^{- 11} m
• C) 9.28*10 ^{- 10} m
• D) 3.88 *10 ^{- 12} m
