For number 4, I've uploaded the raw data if you'd rather process everything numerically. You can find it here. Finding the peak wavelength and area under the curve might be much easier working from the raw data, if you know how to do numerical integration ...
Keep in mind that the intensity for the 60V curve is still multiplied by 2, as in the plot. When you find the area under the 60V curve, you will therefore have to divide by 2 ...
UPDATE: there is an excel file there as well with the data already imported ...
UPDATE 2 (10:25pm): I made a mistake when making the excel sheet and raw data files, and the 80 and 100V data were accidentally scaled to a max intensity of 1. That is fixed now, but if you downloaded the excel sheet or raw data files before ~10:20pm, you should grab them again ...

we're not doing 4b correct?
ReplyDeleteIf the excel sheet or data file you downloaded has a maximum intensity of 1 for any of the curves, then you should grab the new data. If they all have intensities that peak at 1000 or more, you have the right data.
ReplyDeleteIf you already did everything with the data I uploaded earlier, send me a quick email/IM and I can tell you how to fix it without starting over.
But, no, you are probably not doing it wrong ... If you downloaded the old data, and it has a maximum of 1, all you'll have to do is multiply your results.
ReplyDeleteFor each curve that has a max of 1 in your data, read the correct maximum from the plot included in the problem set. Multiply all your data by this number, and you're good to go.
