thank god i found this channel, yall saved my exam

[@izzy1186]

I would like to give u all the credit for helping me throughout my A level journey. You are great people and may god bless you in every way possible. Thank you for your hard work, it is very appreciated !

🤭😅omg i got scared for a sec as i clicked on the vid, i love ur style so much. You're so funny and teach so nicely. Please keep it up!

atoms initially of cold gas at stable state passing white light causes electrons to excite and become unstable electrons drop to their lower initial energy level to return to stable state 1-Electrons absorb energy from specific white light photons 2-electrons excite and move to higher energy 3-energy of photon absorbed = to differnece in energy between energy levels 4-exited electrons must stabilise and return back initial energy level 5-hence electrons emit photon in all directions instead of original direction of scope of screen thus not getting detected on scope of screen

She is more excited than that electron

[@ameeryaqoob3792]

Amazing explanation thankyou

[@haiderisamess]

hi miss, in the absorption spectrum, how does the energy released by an excited electron, in the form of a photon not go in a random direction, why is it visible straight onto the absorption spectrum?

EXCITED YAAAA

[@teeshajairam5741]

Why do waves form at energy levels only

[@ETphysics]

Tip: think about stationary wave harmonics ;)

Wanted to say big thankyou to you for being their in journey of my a levels.. I could not imagine how my life would've been with out you both.. THANKYOU SO MUCH.. I gave my paper day before yesterday and I think it went pretty well.

[@jojuliet]

I used wavelength = h/mv instead of e=hf 😭😭

So the electron is like us. More attractive girls we get excited, ugly girl we don't get excited😂
