Question

what causes the bright lines seen in the emission spectrum??

Answer 1

Well....the emission spectrum, kowing somethings that I believe to be what it sounds like, are either some type of "wave" that cannot be sound, therefore for us to see it, although with no sound, I guess it must be some other kind of wave, that vivrates at diffferent frequencys, now, the source of this is porbably something that produces light, like a prism maybe, ah, therefore I think that what causes this color to be seen is because when light hits theprism, and if I remmember, a prism emits light like a strraight rainbow coming out of it, or does it? I wonder, however, then there must be a change of frequencys chancing as light is inside the prism, that would explain why A, it doesnt spit out light but spits out a dispersed version of it unlike that dumb wolfmother album called dark side of the moon. Anyhow, the more the light reflects inside the prism, I have surmised that the less the frequency changes inside the prism, therefore that would explain the several layers of light, especially the violets.

I got this all wrong didn't I....

Answer 2

WELL SHIZ....OMGomgomg....

Answer 3

nvm I got this all wrong....

Answer 4

i dont get this topic

Answer 6

ohkk...yea but why does h2 gas give light when heated??

Answer 7

h2 gas is given energy or photons when heated ,so electrons must absorb all the photons and get excited..light is are given off only when electrons relax to low energy levels and emit photons..

Answer 8

When you heat a substance, it excites the electrons. They go to higher energy levels and absorb light. When they come back to a lower energy state, they emit light.
Light is emitted in the form of photons

Answer 9

yea ..so h2 gas is heated ..so why is it emitting light??

Answer 10

they must get excited....not relaxed

Answer 11

Well when you heat h2 gas, it DOES excite the electrons and bring them to a higher energy level, but they must also fall back to a lower one after.
If they go up, they will come down

Answer 12

but h2 gas emits light immediately when its heated ryt??

Answer 13

Yes. The electrons absorb and emit right away

Answer 14

so electrons relax instantly??

Answer 15

Yes, in a sense they get excited and "relaxed" one after another

Answer 16

okk...so they emit photons or light of certain wavelength..how does this work??

Answer 17

whats ur doubt now?

Answer 18

they have explained it nicely

Answer 19

what causes h2 gas to produce the bright lines in spectra??
A. When photons of certain energies hit electrons, the electrons move to higher energy levels.
B. After being excited to higher energy levels, electrons return to lower energy levels. In the process, they release photons of light of the energies seen in the spectra.
C. When light hits the hydrogen gas, most wavelengths are absorbed by the gas. Only certain wavelengths of light pass through the gas, causing the spectral lines to appear.
D. Most wavelengths of light are invisible to the naked eye. The bright lines represent the only visible wavelengths of light. The hydrogen gas has no effect on this light.
(which option is right?)

Answer 20

i think its B

Answer 21

what do you think bobobobobb??

Answer 22

Yes B

Answer 23

pretty much,wat i wanted to know is this.....

Answer 24

5.An atom of a fictional element has the energy level diagram shown below. Which line will not appear on the total emission spectrum?
A. 0.9 eV
B. 0.8 eV
C. 0.7 eV
D. 0.6 eV

Answer 25

AravindG ,can you help with this??

Answer 26

pls post that question separately and pls dont use OS to do ur homework

Answer 27

i dont have any bad intentions,its just for the future....

Answer 28

if its for ur future make an honest attempt in thse , read ur text again after that if u still have doubt call me @AravindG i will be there to help

Answer 29

@AravindG ??

Answer 30

yep then i will get notified

Answer 31

what are the lines on emissin spectrum exactly??

Answer 32

each line repesents what??

Answer 33

Each line represents an energy level a photon can be excited to. Being that most things in the universe wants to be at the lowest energy state, when the photon eventually falls to a lower energy state, it will release energy corresponding to a spectrum of light.

Answer 34

in case of h2 ,how many levels can it get excited too??
4??because there is only 4 lines on its emission spectrum.......
