Making a graph
Using Excel one the same graph make three scatter-plots of against for three data sets. Show linear best-fit-lines to each scatter-plot. Make sure that the graph has an informative title; also make sure that all axis, scatter-plots and best-fit-lines are properly labelled. On the same graph, show linear equations for each best-fit-line. Note the gradient G for each best-fit-line.
Finding lAVG and Dl
Given that 1 inch corresponds to 25.4 mm calculate the value of d for each data set. Using the equation express the wavelength l in terms of G and other quantities. Calculate the value of wavelength for each gradient and find lAVG. Given that your gradient has no errors, calculate ∆ using the error propagation formula (recall the lecture on error analysis). State your result in the following form lAVG±Dl. 1 | 2 | 3 | 4 | 5 | Поиск по сайту:
