    When atoms in atmosphere absorbs radiation(solar flares) coming from the sun it gets excited and when returns to its original state it emits beautiful lights in sky...

    I have a doubt.....why does absorption spectrum even exist, if the electrons absorb the energy from coming photons it means they will go in an excited state...that means that they will again radiate a photon to come back to the ground state...since we know that electrons become unstable in higher energy level...so the photons emitted should fill up the dark linesbut ut doesnt happen.

    To find the number of unique spectral lines we can use the concept of combinations(mathematics) for example if an electron is falling from 3 to 1, number of unique spectral lines are 3c2 which is 1 , if an electron is falling from 4 to 1 then 4c2 which is 6.

    Energy emitted =En2-En1
    Aur sir ne (En2 - En1 = hv) kar diya
    Iska matlab jab electron excited se ground mein aata hai wo sirf ek photon release karta hai kyunki hv ek photon ki energy hoti hai..... Aur hv agar (excited state energy - Ground state energy) hai toh wo ek hi photon ki energy toh hui.... 🤔🤔..
