I just said 'the sun has mainly hydrogen in it' (probably in better words) and that was all I really mentioned about the sun. Shows my deep understanding of it xD

I wrote "It got absorbed" as a very last-minute thing (right as they said "Pens down", whilst I was flicking through my exam to see if I had any incomplete answers). And seems like that's actually partially right... I wonder if they'll give me one mark for that? :D

Ahmad:
Well absorbed is probably a keyword. So you might just get a mark. ^^

Galelleo:

--- Quote from: "abcat" ---the hydrogen/sun question was a joke.

the study design does not state a requirement to know the composition of the atmosphere of the earth.

i got the answer, but not doing chemistry (assuming that's the subject where you would learn this stuff) i thought it was a tad unfair.

I disagree....how do you think they figured out that the sun had hydrogen in it?

we see the hydrogen emission spectra as having 2 spots that fit right in with the gaps in the suns absorption spectra...t his TELLS you that the sun/atmosphere has hydrogen in it.

Indeed, and they made it so obvious as well.

"Here is a zoomed up version that has lines in the same spot as the spectra we're about to ask you about..."

Might as well have wrote it in massive letters across the page.
