Page 10/11? In this case the gradient is h/e where e is the charge on the electron. Even if that's not you're paper are you able to adapt the principles used here? Could you please post the exact question as well.

sorry i posted the wrong q! i found my mistake .. and the actual q is to show that from eV=hf-fi that hc/e is the gradient..
