I am trying to help my son in his year 12 physics. I know very little of this(adsbygoogle = window.adsbygoogle || []).push({});

can someone please assist.

find in eV (electron volts) the energy of a proton with a de broglie wavelength of 40 pm (picometres)

What would the correct formula be ?

A good chance for me to learn as well ;)
