A) If the De Broglie wavelength of an electron is equal to 250 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 910 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.
