Photoelectric Effect

Experiment: Photoelectric Effect prevail Name/Section: physical science 222 Section 012 Date: April 12, 2012 Conclusion The flip of the first regularize grace potentials was 0.3753 which yielded an h set of 6.0048x10-34Js, which was 9.38% get rid of of the accepted h rank of 6.6x10-34Js. The second cast fillet potentials flip was 0.4255. This yielded an h value of 6.808x10-34Js, which was 2.75% polish off of the accepted h value. in that respect were many sources of wrongdoing in this experimentation. The percent demerit is practic every(prenominal)y higher for the first order stopping potential than for the second. This whitethorn be due to the occurrence that the lamp was non fully alter when the measurements were bourgeonn. in that location was not a guess anywhere to identify when the lamp was fully heated, so it was more of a guessing crippled than anything. another(prenominal) source of error whitethorn ingest been the ambient escaped in the lab. This may keep entered the detector during the experiment, skewing the data.

This is an experiment that involve to be performed in wide-cut darkness, but it was not assertable due to the blinds not block off out all of the sunlight and the computers being on passim the experiment. A final exam cause of error may have been the yellow and potassium filters2. They have been inadequate, insufficiently occlude high frequency light. These unwelcome high energy photons would have ejected high energy electrons, allowing them to go through the cathode-anode potential, which would have increased the mensurable stopping potential.If you want to take a full essay, order it on our website: Ordercustompaper.com
