To determine the work function of a material of a photodiode, you measuered the maximum Knetic energy of .5 eV correwsponding to a certain wavelength. Later on, you cut down the wavelength by 50% and found the maximum kinetic energy of the photoelectrons to be 3.8eV. From this information determine
a) work function of the material, and
b) the original wavelength.
