Find the kinetic energy (J) of an electron which has a de Broglie wavelength equal to 605 nm.
= wavelength = 605 x 10-9 m
m = mass = 9.1 x 10-31 kg
using de broglie formula
= h/mv
v = h/(m)
v = (6.6 x 10-34) / (9.1 x 10-31 x 605 x 10-9)
v = 1198.8 m/s
Kinetic energy = (0.5) m v2 = (0.5) (9.1 x 10-31) (1198.8)2 = 6.54 x 10-25 J

A) If the De Broglie wavelength of an electron is equal to 350 nm calculate the velocity of the electron. Assume that the electron's speed is non-relativistic. B) If the kinetic energy of an electron is 440 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.

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.
