Spectrum Images of Light Sources

Here are some aquired spectra of common light sources. There are generally two kinds of light found in the world: I aquired these images with a diffraction grating held onto a small plastic tube--you can see the slit in the end of the tube on the left side of each image. I just held my digital camera up to the tube by hand, so each aquired spectrum is at a slightly different orientation. A decent, calibrated spectrometer is only $40--I need to invest in one!
