Answer:

I would say by using Einstein's Formula: #E=hf#

Explanation:

If you have the wavelength #lambda# of the photon needed to take an electron away from the atom you can use it into:
#E=hf#
where #h# is Planck's Constant and #f# the frequency.
Knowing that for the speed of light you have #c=lambdaf#
and so:
#E=hc/lambda#
