Tim Greenway Photo Electric Effect - Making Sense of Data Brief: I took part in a class experiment on the photo-electric effect. We gathered lots of results which can be used to calculate several values, such as the value of Planck's Constant. My task is to make sense of the data obtained by interpreting, analysing and manipulating the data from this class experiment. We did four repeats obtaining results from six different colour bands. I have to communicate my results logically, using ICT where appropriate. Apparatus: In the class experiment we used a unit developed by the University of Newcastle-upon-Tyne and Rutherford College to provide a simple method of calculating Planck's Constant. I can't expect a high order of accuracy, due to the inexpensive production process. It analyses different energy levels over the range of the visible spectrum by using different coloured filters between the light source of the photo-tube. The reverse voltage is controlled...
