If the de Broglie wavelength of an electron is 7.3 μm, what is the speed of the electron?
a1.0 × 102 m/s
b2.7 × 106 m/s
c5.5 × 102 m/s
d8.2 × 104 m/s
Solution)
We know,
Wavelength, lambda= h/mv
So, speed, v=(6.6*10^-34)/(9.1*10^-31 kg)*(7.3*10^-6 m)
V=1*10^2 m/s

If the De Broglie wavelength of an electron is equal to 400 nm calculate the velocity of the electron. Assume that the electron's speed is non-relativistic. Answer: 1832.42 m/s If the kinetic energy of an electron is 400 eV, calculate its De Broglie wavelength. For this non-relativistic electron you must first calculate its velocity from the general kinetic energy equation. Then you can find the De Broglie wavelength of the electron. I cannot figure out the second part, please explain!
