thanks for the hint. Well E=h*c/w =1.32E-17 J => 82.7 eV
So... Yes it will be ionized, and the kinetic energy should be 82.7-13.6 = 69.1 eV.
Is this right?
PS=don't know if this forum have an uniform use of the constant, in my calcolous:
h=planck costant, c=Speed of light and w = wavelenght
This is the exercise:
Suppose that an hydrogen atom in its ground state absorbs a photon whose wavelength is 15 nm. Will the atom be ionized? If so, what will be the kinetic energy of the electron when it
gets far away from its atom of origin?
i have no idea how to procede! Someone can help...
