Hi everyone, I can't seem to calculate Planks constant (h) from this graph. I thought it should simply be the gradient? So I used h= (f1-f2)/(Ua-Ua2) but found it to be nothing near the actual constant of 6.63*10^34!(adsbygoogle = window.adsbygoogle || []).push({});

Any help would be greatly appreciated!
