1. Problem: If the de Broglie wavelength of an electron is 555nm, what is its velocity?(adsbygoogle = window.adsbygoogle || []).push({});

2. Relevant equations

- λ = h/mv

3. Ok so i first did the amu-g conversion. so i got the mass of the electron is (9.13297 x 10^-28g), then i did nm-m conversion so (555 x 10^-9m) and i multiplied them and then divided by plancks constant but i got the wrong answer?
