FREE Expert Solution

We’re being asked to calculate the de Broglie wavelength of an electron


Recall that the de Broglie wavelength (λ) can be calculated using:



λ = hmν


where:

h = Planck's constant (6.626 × 10–34 kg • m2/s)

m = mass (in kg)

v = velocity (in m/s)


We’re given:

mass = 9.11 × 10-28 g           velocity = 7.40 × 106 m/s
