1. Frequency is measureed in units of ___, and the ___ of a substance is the set of wavelengths absorbed/emitted by that substance.

2.In a cathode Ray Tube, What is the Electron Stream Called

3.What is the theoretical partticle exchanged by quarks?

4. When mass and relative isotopes have been found, the average ___ can be found.

I'm pretty sure #4 is atomic number but the rest i'm clueless.  If you can't answer these could I please be directed to a site with this info that's not utterly confusing. Thanks!

Ok..I got #3 thanks to Arkcon, and i got #2 also.  Any help on #1, and was i right with #4?

Ok...now I just need #4. Pleeeeeeeease?

3.What is the theoretical partticle exchanged by quarks?

I didn't know the answer to this one.  So I plugged it into Google.  First Google corrected the misspelling.  Then I got this:

Either you want the theory behind the answer, or you don't.  But the answer is right there on the search page.

'Tho I have to grant you one point, the wikipedia entry on Cathode Ray Tube is pretty messy, you're not going to find your obscure definition there.  I would suggest perusing your (or someone else's) class notes.  Some of the facts you need are kinda, well, not facts, just different ways of saying things.

4) is the average atomic mass, assuming you meant the relative abundance of isotopes in your question.
