Given:
Mass of person ,m = 79 kg
Speed ,v = 1.4 m/s
de Broglie wavelength is given as:
= h/( m *v)
where h = Plank's constant = 6.626 * 10 -34 m2 kg/s
= 6.626 * 10 -34 / ( 79 * 1.4)
= 5.99095 * 10 -36 m

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!
