How to calculate the de broglie wavelength
WebFor example, we can find the de Broglie wavelength of an electron at 100 EV is by substituting the Planck’s constant (h) value, the mass of the electron (m) and velocity of the electron (v) in the above equation. Then … WebWorked example: de Broglie wavelength A proton and an electron are each accelerated from rest through the same potential difference. Determine the ratio: $ \frac{\text { de Broglie wavelength of the proton }}{\text { de Broglie wavelength of the electron }} $ Mass of a proton $=1.67 \times 10^{-27} \mathrm{~kg}$
