wavelength value in nm for spectra lines formed in HE

#8158157 - 03/17/08 04:51 PM (16 years, 1 month ago)

What are the theoretical values for wavelength(nm) for spectra lines formed in Helium (HE)? I can't find these values anywhere. I need a source too. The colors are Red, Yellow, Green, Blue, and Purple. Thanks.

I'm not sure what exactly you're asking for, but this may be it:

2) You can't have an abortion no matter how much you don't want a child.
3) You can't have a certain plant in your possession or you'll get locked up with a rapist and a murderer.

4) We need a smaller, less-intrusive government.

The above explains the origin of the lines and the wavelength for each

that's from mcgraw hill, quality secondary source

do you need the actual study that produced experimental values or something? If so just search google scholar till you find something.

If this isn't what you need you'll have to explain what you want better
