Hi im currently trying to write up a lab report for my 3rd year lab on the scintillation counter and im struggling to convert the error i have for the gradient and intercept (using polyfit on excel) and the uncertainty i have in my x values, to the uncertainty in my energy measurements where energy=mx+c. c is the y intercept and m the gradient. The x value here is the channel number for the photo peak with an error of plus or minus 2, My gradient is 0.0037 with error 0.0002 and intercept -0.0187 with error 0.005. How do i get the error in energy from this, note the uncertainty in channel number was always 2 despite it ranging from 40 to 400. any help would be much appreciated.(adsbygoogle = window.adsbygoogle || []).push({});
