Aljaniis trying to experimentally measure Planek's constant h. He does this by shining different wavelengths of monochromatic EM radiation on a metal plate with an unknown work function W and then measuring the stoppage voltage required to bring the ejected electrons to a halt. When he uses frequency =400 nm, he finds that a stoppage voltage of V1=.7V is required. When he uses frequency2=500 nm, he finds that a stopping voltage of V2=.2 V is required. Based on these two data points, what is Ajanis measurement of Planek's constant?
