Description
Physics from it's most beautiful side: Spectrum analisis of Mercury combined with Cadmium.

What is this ?:

This is the spectrum of a mercury/cadmium lamp. The light had been transfomed into a line with a gap. With a collimator and a prism (mounted on a gonimeter) the different wavelenght had been seperated because of dispersion, so you could see every line in relation to it's wavelength. This you could observe with a telescope.

1 line 643.85 nm (red) Cd
2 line 576.96 nm (yellow) Hg
3 line 546.07 nm (green) Hg
4 line 508.58 nm (blue-green) Cd
5 line 479.99 nm (blue) Cd
6 line 467.82 nm (blue) Cd
7 line 404.65 nm (purple) Hg
8 line 365.02 nm (purple) Hg

I took the picture simply putting the camera in front of the eyeglass of the telescope.

Feel free to comment !
