Photoelectric Effect Java Applet modeling e*Vs = h*f - W

To model this equation.

Ekin = h f – W

Ekin ... maximal kinetic energy of an emitted electron
h ..... Planck constant (6.626 x 10-34 Js)
f ..... frequency
W ..... work function.

I am exploring whether this is a good applet to port over to Ejs format. I used to use this in 2006 and it worked fine, strangely now it is not plotting the lines.

i used to be able to vary the 5 options of light wavelength and it will plot the points automatically and when all points are plotted, it will draw a line to show

e*Vs = h*f - W

it used to show the line but strangely it doesn't run properly now.

i don't think i can make this one myself, so i have to request for this

By the way,

is a I vs V graph, i wonder can it be remix for e*Vs =  h*f - W ?

Please check out Photoelectric effect
It is designed to be similar to a real experiment.
User need to repeat the operation several time with different work function and extract data from the simulation
 to get e*Vs = h*f - W relation.

ok i try to remix this one into e*Vs = h*f - W
