Find the kinetic energy of the following particles that each have a de Broglie wavelength of 0.50 nm.?(adsbygoogle = window.adsbygoogle || []).push({});

(a) photons

____eV = 2480eV

(b) electrons

____eV

(c) neutrons

____eV

(d) α particles

____eV

i know E= hc/wavelength which = a and after that im stuck i know that the wavelength = h/p but i dont know how to solve the others with this
