SUMMARY

The discussion centers on the photoelectric effect experiment conducted in a physics class, where the stopping voltage was measured at various light wavelengths using filters. The participant aims to derive conclusions related to Planck's constant (h), threshold frequency, and work function from their graphical data. Key equations discussed include f0 = W/h and W = hf0, which relate frequency and work function. The participant seeks deeper insights into the relationship between independent and dependent variables as observed in their experiment.

Homework Statement


So I recently performed the photoelectric effect experiment in my physics class, where we measured the stopping voltage at different wavelengths of light by using filters with different levels of grating.
I measured the stopping voltage and plotted them on a graph against frequency to gain values for (h) experimental Plancks constant, threshold frequency and the work function

I have come to the point where I need to write a conclusion but I can't think of anything that I have concluded by the use of these formula, which supports my hypothesis.

Homework Equations


f0 = W/h
W = hf0


The Attempt at a Solution


I know that as the wavelength of light is changed , it will cause a change in the stopping voltage. But I need a way to explain this in terms of my graphical data, which evaluates the information I recorded by observing the experiment. So far all I can conclude is that a change in the independent variable causes a increase or decrease in the dependent variable which was expected.

I need some more key points which show a deeper understanding of the concept in this experiment and the photoelectric effect.
Can anyone point me in the right direction to what I should be looking for and discussing in this report?
