12. [GilChem2003 3.P.034.] The light from a particular star is redshifted by 23.9% and includes
the Balmer series of H emission lines. Calculate the wavelength for the line arising from the transition from n = 3 to n = 2 as viewed from Earth. Thanks. Mtechgunman |

2+2=5 for large values of 2 |
|

|
lambda(n,k) = (limit) * n^2 / n^2 - k^2 For the Balmer series, k=2 with a limit of 365.4nm. I would think that you would need to adjust the limit (which corrisponds to the lower limit of the optical spectum of Hydrogen) to account for the red shift and rerun the numbers for the given values of n. |

FUCK IT!!!! I AM QUITING COLLEGE AND GOING TO WORK AT TACO JOHNS!! FUCK THE BULL SHIT!!!!
|
|
WTF classes are you taking that include spectroscopy? |
|

Chemistry
ETA: thanks, the answer is correct. at least it helped me get there!!! |
|
I was wrong (kinda). For the 3-2 transition, the wavelength is 6563 angstroms, so shift that to the red by 23.9% and I think that is the answer. |

Ha you simple fool... |

Alizee is a bandwidth thief! SCANDALOUS! |

i bet you think you were in the popular group in high school, dont ya??

Don't look at me - I haven't set foot in a physics classroom in over seven years. Don't ask me how many time I punted Physics...damned math.... |

Hello,
Wow what an odd question to find here on this type of forum. Anyhow I will help get you started. The Johann Balmer series (i.e. H alpha, H beta, H gamma, H delta, and etc.) was founded by Balmer in 1885 where he found that the plot of the frequencies of the hydrogen emission lines is linear as a function of 1/n squared. More to the point, in the case of the N3 to N2 electronic transition you will need to specifically employ the use of another dude’s equation by the name of Johannes Rydberg where this will yield the longest wavelength of 656 nm. Now the fun part Redshift that beeoich by 23.9% Regards, Tgrds |

Tgrds.... There is no question arfcom cant answer..... We are the world.... from Hollywood to Headline World News. From Astrophysics to Antartica, from AR15 to AK47. I repeat, there is no question arfcom cant answer.... |

Ain't that the truth!!!!! |

Don't worry about getting good grades in school, always remeber this:
- No matter how hard you try... some fucking Towel Head will get a higher grade - No matter what major you choose... that job will be outsourced in 5 years - No matter how qualified you are... some minority will get your job - No matter how good you think you are at "pulling out".. the girl is going to get pregnant and you will end up with four kids, a fat wife, three dogs and a paraket all living in a 20 ft. steamlined trailer. So, you see, in the long run... phase shifts of stars and the calculable wavelength of certain star emissions are all irrelevant. Oh, by the way... the answer is "UMM BOP... WOW CHU WOW DOO WOP.. BLEEWB BOW DOW EWW WOW WOOOOO" LOL... Sorry, I'm tired. |

If you don't hang in there, keep plugging away and study or you WILL be working at Taco Johns - forever! P.S. - I forgot to mention that the pay at Taco Johns is not adequate to support your participation in the shooting sports? |

Sorry, but what SmokyCity posted is rather funny... and I thought I would make him feel better by pointing that out.. Way to get 'er done

Forgot something: -I will be living in a van down by the river. |

This type of forum? Hah. Much to learn has this one. |

I think I have a question you may not be able to answer:
What is the "Measure of a Man" - By Clay Aiken? Also... Who puts the fuzzy lint in my belly-button when I'm not looking? Furthermore... I can't feel my legs...? And, no.. I'm not sitting on them... Note: Actually can feel my legs... thanks for caring though. |

#1 a song by Clay...
If one day you discover him Broken down he's lost everything No cars, no fancy clothes to make him who he's not The woman at his side is all that he has got Why do you ask him move to heaven and earth To prove his love has worth? Would he walk on water Would he run through fire Would he stand before you When it is down to the wire Would he gave his life up To be all he can Is that, is that, is that how you measure a man? If by chance all he had to give you Was three words wrapped around his finger Would that be deep enough at the end of every day And how will you ever know If a man is what he says? Why do you ask him to move heaven and earth To prove his love has worth Would he walk on water Would he run through fire Would he stand before you When its down to the wire Would he give his life up to be all he can Is that, is that, is that how you measure a man? He never gives up Lets go of his dreams His world goes around for his one true belief Is that how you know Is that what it means? Would he walk on water Would he run through fire Would he stand before you Would he will be your anchor when the dark unfolds Would he always love you the best that he knows? Would he give his life up To be all that he can Is that, is that, is that how you measure a man? Would he walk on water Would he run through fire Would he stand before you When it is down to the wire Would he gave his life up To be all he can Is that, is that, is that, how you measure oh... Is that, is that, is that, how your measure a man? -------------------------------------------- #2 belly button gnomes put the lint there ---------------------------------------------- #3 dont understand about the legs, sorry need more info. / get well soon? |

Also.. I know what Jane says and I would tell you... BUT... aww.. shucks.. I'll tell ya:
Jane says I'm done with Sergio He treats me like a ragdoll She hides The television Says I don't owe him nothing, But if he comes back again Tell him to wait right here for me Or just Try again tomorrow I'm gonna kick tomorrow Gonna kick tomorrow Jane says Have you seen my wig around? I feel naked without it She knows They all want her to go But thats O.K. She dont like them anyway Jane says She's goin away to spain When she gets my money saved She's gonna start tomorrow I'm gonna kick tomorrow Gonna kick tomorrow She gets mad Starts to cry She takes a swing but She cant hit She don't mean no harm She just don't know What else to do about it Jane goes To the store at 8:00 She walk up on St. Andrews She waits And gets her dinner there She pulls her dinner From her pocket Jane says She's never been in love No, she don't know what it is Only knows if someone wants her I want them if they want me I only know they want me She gets mad And she starts to cry She takes a swing man She cant hit! She don't mean no harm She just dont know What else to do about it Jane says Jane says |
