Question

Calculate the de Broglie wavelength of an electron moving with velocity $ 6 \times 10^6 \, m/s $. (Mass of electron $ m = 9.11 \times 10^{-31} \, kg $, Planck's constant $ h = 6.626 \times 10^{-34} \, Js $)

• A. \(1.2 \times 10^{-10} \, m\)
• B. \(1.1 \times 10^{-10} \, m\)
• C. \(1.0 \times 10^{-10} \, m\)
• D. \(0.9 \times 10^{-10} \, m\)

Hint:

Tip: Carefully handle powers of ten in calculations involving quantum scales.
