Balmer Series Lab 11/3/08We 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:
