Emission and Absorption Line Spectra - A Level Physics

From earth, we can figure out the chemical composition of a star looking at the absorption spectrum it produces. But why do we see absorption spectra from stars? A star is a source of light. Studying its light waves through a spectrometer or a prism, we will find a continuous spectrum. A continuous spectrum is made up of a continuous range of wavelengths.
A star like our sun emits photons of all frequencies to produce a continuous spectrum. But before these photons reach us on Earth, some photons get absorbed by the cooler gas around the star. The gas can then re-emit photons, giving us the emission spectrum if we can isolate just the gas and look at it through a spectroscope. But looking at the sun light that has passed through the gas, then we will get the absorption spectrum.
In other words, the photons that form the absorption spectrum are the ones that did not get absorbed by the gas.

Honestly I have never easily understood Line Spectra, however you simplified it to a level to where it’s understandable, huge respect!

[@NoahIbraheemAOT]

This 2 minute video explained more than me reading the same 2 pages for 10minutes. Tyyyy

[@samiaaktermohima84]

It would be better without the music☺️

[@tauruswabi5326]

Why did you even concern about it ? You should train your brain to concentrate only on a specific thing. Pls I'm advising you. Becouse when i saw it i was only listening to her . So you should to

@@tauruswabi5326 you are great, you the best. Everyone should have your standard level of concentration before watching a video on youtube.

@@tauruswabi5326 girl it aint that deep... the musics just annoying

[@omarwasim4911]

Bruh took me 10 minutes to understand the damn thing and this lady explained it in 2 minutes. I need a much bigger brain LOL !!

we need more people like you venessa.

[@mustafakamalrahi]

Wow beautifully done! Keep up the good work 👍🏻

Qué explicación tan clara y sucinta! Felicitaciones y muy agradecido por el video! Sigue así 🎉

[@honeyvirdi1646]

i have my exam tomorrow and this has helped sm thank u

[@diamond-ge7td]

really explained better than my notes. thank you !

[@ahmedalrafi500]

the perfect explanation with the least bit of time

[@squigggie3]

Very helpful! Thank you! My science teacher has a very strong accent, and I did not understand when she taught my class this. 😂

[@anii6665]

I loved your explanation It was so clear Love from S India😊

[@letsexplore1160]

Explained so good I a very short time
