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:
We learned the behavior of electromagnetic radiation due to a simple antenna. The voltage and distance is the mots important two things. The range of error between the two could be explained by discussing
the simplifications made in order to keep this experiment simple. Even though we
assumed that the linear charge density was constant, there were also other
outside interference that could have altered the effects of the radiation that
would have given slightly inaccurate data from the oscillator.
