We then observed the wavelength lines for the hydrogen lamp. Again turning the dial counter-clockwise, we saw the following four lines:
The hydrogen lamp was quite hot after I turned the lamp off.
We then observed the following emmision spectrum for the deuterium lamp:
Two astonishing things occurred:
We then observed the spectrum of a krypton lamp (the originial lab called for sodium, but sodium wasn't available and Aram suggested krypton) in order to determine how well we could resolve separate spectral lines. On the violet end of the spectrum (with many lines), I was able to resolve to roughly 1 nm to differentiate separate wavelengths.
