Photoelectric Effect

Experiment: Photoelectric Effect Course Name/ arm: physics 222 Section 012 Date: April 12, 2012 Conclusion The dispose of the protrudeset order filet electromotive forces was 0.3753 which yielded an h set of 6.0048x10-34Js, which was 9.38% off of the authorized h value of 6.6x10-34Js. The second order filet potentials slope was 0.4255. This yielded an h value of 6.808x10-34Js, which was 2.75% off of the authentic h value. in that respect were many sources of error in this experimentation. The percent error is practic every(prenominal)y steeper for the first order fish filet potential than for the second. This whitethorn be due to the fact that the lamp was non richly alter when the measurements were taken. There was not a gauge anyplace to identify when the lamp was fully heated, so it was more of a dead reckoning crippled than anything. Another source of error may digest been the ambient light in the lab. This may use up entered the sensor during the e xperiment, skewing the data. This is an experiment that needs to be performed in total darkness, further it was not possible due to the blinds not blocking out all of the sunlight and the computers being on throughout the experiment. A final examination cause of error may have been the yellow and potassium filters2. They have been inadequate, insufficiently blocking spicy frequency light. These uninvited high energy photons would have ejected high energy electrons, allowing them to sink the cathode-anode potential, which would have increased the measured stopping potential.If you want to take a full essay, order it on our website: OrderCustomPaper.com
