I'm reviewing for one of my final exam and I can't seem to figure out this problem:(adsbygoogle = window.adsbygoogle || []).push({});

Find the Debroglie wavelength of an electron with a KE of 40 ev.

I got an answer of 3.9 x 10^-10 m.

I keep getting it wrong and I'm not sure what to do.

Thanks in advance!
