Any of the choices is the correct answer
The maximum energy of photoelectrons from aluminum is 2.3 ev for
radiation of wavelength 200nm and 0.90ev for radiation of 216nm.
Then the planck's const ant and the work function of aluminum iss
h=2.016x10-33j.s
and
W= 16.6 ev IO
h=6.63x10-34j.s
and
w= 16.6ev II O
and
w= 15 ev IIIO
h=20.16x10-36.s
