Planks Constant
Measurement of the Plank constant is an important objective in physics. The constant is important in many areas, especially in quantum mechanics.
Data
[math]\displaystyle{ h_{meas} = 7.26(14)\cdot 10^{-34} J \cdot s }[/math]
[math]\displaystyle{ h_{act} = 6.626\cdot 10^{-34} J \cdot s }[/math]
[math]\displaystyle{ W_{meas} =1.635(48) V }[/math]
[math]\displaystyle{ W_{act} = 1.36 V }[/math]
Conclusions
- Although I am happy with our results, I am not particularly happy with the lab set up. I believe that we got good data, given that it fit perfectly to a straight line. I believe there is some source of systematic error that prevailed in this lab.
