http://lnk.nu/google.co.uk/28fr Are results that come from a spectrometer such as the image above continuous? I ask because I need to find the area under a spectrum. If the data points are continuous then I would use integration, if it's discrete then I would use a summation. I've confused myself as even though a continuum of wavelengths in an interval are applied to a molecule, surely it is impossible to record the absorption at every value in a that interval.
