Photoelectric effect -- experimental
Suppose you are doing an experiment to determine the work function of a metal.*
You get k.e.$_1$, $\nu_1$ and k.e.$_2, \nu_2$.
*
We know that k.e.= $h\nu - W$ but when you solve the simultaneous equations, we have a $h$ slightly different from the textbook value.
Question: In such a situation should you
a) Use the textbook $h$ then average {$W_1,W_2$}; or
b) Simply solve the simultaneous equations for $W$
I believe that the values obtained will be different. And no further experiments are done.
Thank you.
