UNCERTAINTY ANALYSIS:

The uncertainty values for the peak to peak voltage are as follows:

±12 for V= (50 mV, 90 mV)

±6 for V= (19 mV, 28 mV)

±3 for V= (7.5 mV, 15.5mV)

The quantization uncertainty in the measurements of the distance z was set to ±0.01 cm. However, this uncertainty distance that was measured may have been calculated to the base of the prong. Consequently , an additional uncertainty, ±.02cm, needs to be added making it a total ∆z uncertainty of ±0.03cm.

Conclusion

Based on the results we got, we verified the concept of EM waves. There were many assumptions that were in constructing the model of the theoretical voltage. The charge, Q, was considered to being a constant value throughout was one assumption that led to a comparable theoretical set of data numbers. The range of error between the two could be explained by discussing the simplifications made in order to keep this experiment simple. The data between the experimental and the theoretical were all in the range of uncertainty.
