Homework Statement
I am trying to plot a graph of stopping voltage against frequency
The given equation is eV0 = hf - w0
So i need to change it to the form of y = mx + C in order to plot this graph
V0 = h*f/e - w0/e
V0 = h/e * f - w0/e -- > V0 = y , m(gradient) = h/e , x= f and -w0/e = C (y intercept)
V0 is the stopping voltage , h is Planck constant , e is the electron constant , W0 is the threshold frequency
Now I am confused what SI unit does h/e has and w0/e ?
