Unformatted text preview: Then tmake a plot of sin(theta) vs. p*lambda (where p is the order -2, -1, 1, or 2), and fit a line to the data to get a slope (1/a) and the error in 1/a as well. you should make four measurements for each of the two lines in sodium, and four measurements for each of the probably four lines that you can see in hydrogen. For each individual line you should do a plot of sin(theta) vs. p to get lambda/a, and that will give you all your lambdas and sigma_lambdas. Then find a lambda average and delta lambda for sodium (compare to Lab 4 - the result is interesting!) And for the Balmer series you can fit 1/lambda to 1/n^2 to get the slope and intercept giving you the Rydberg and the 1/2^2...
