🤓 Based on our data, we think this question is relevant for Professor Lapeyrouse's class at SEMINOLESTATE.
We’re being asked to calculate the de Broglie wavelength of an electron.
Recall that the de Broglie wavelength (λ) can be calculated using:
h = Planck's constant (6.626 × 10–34 kg • m2/s)
m = mass (in kg)
v = velocity (in m/s).
mass = 9.11 × 10-28 g velocity = 7.40 × 106 m/s
The de Broglie wavelength of an electron with a velocity of 7.40 × 106 m/s is ________ m. The mass of the electron is 9.11 × 10-28 g.
A) 1.02 × 1010
B) 9.83 × 10-14
C) 1.02 × 1013
D) 9.83 × 10-17
E) 9.83 × 10-11
