Homework Statement
Not sure whether I should be posting this here or in the quantum physics thread but I felt this more of a 'homework' question.
So basically I have done an experiment in which I measure the energy of light that has been scattered through a steel rod from a radioactive source. The software used to record this saves the data as a text file with columns (energy(Kev) and impulses). There are about 3000 entries as it was required to record data for about 24 mins. The problem is I am supposed to graph this data and show the Compton effect but when ever I select the data and click insert graph it tells me "the maximum number of data series per chart is 255" and I'm unable to insert a graph.
I have tried researching this problem but I can't seem to fix it. The instructor during my lab also told me to just save the data as a text file and go home and insert it into excel. So I'm not sure what I'm doing wrong. Am I going to need some other software to do this?
My second question would be once I figure out how to graph this how would I interpret the data? From what I know the first peak is the incident wavelength and the second is the shifted wavelength. However I was under the assumption that it was the peak(maximum) energy that corresponded to the shifted wavelength as that would indicate it hit an electron that was stationary. So I'm confused as to how the impulses is used in this as this just indicated how many time that energy was recorded right? Not the maximum energy recorded.
I'll upload a screen shot of the data recorded for a 30 degree scatter angle.
Any help is greatly appreciated.
Thanks
