Here enegy gap goes on decreasing as e2-e1> e3-e2> --------so value of wavelength goes on increases right ......plz check first enting energy le

SO On. y be obtained as follaws n = 5- -52-5 kJ mo -82-0 kJ mol n= 4- L n 3 -145-8 kJ mol 328 kJ mol n = 2- C4) -1312 kJ mol n = 1- Reposenting energy levels of H-atom and spacing between them ls go on decreasing as we move outwards.

    yes, wavelength will increase as energy difference decrease

    eduncle-logo-app

    E= hc/ lemda so Energy is inversely proportional to wavelength

    eduncle-logo-app

    but this question

    eduncle-logo-app

    for shortest wavelength Energy difference will be high na ?

    eduncle-logo-app

    check it

    eduncle-logo-app

    n2 infinity kyin hai yhan n2 means second shell means energy in sencon aise Lena Chahiye tha

    eduncle-logo-app

    pr yha shortest wavelength puchi he na , so energy gape maximum kb possible he jb electron infinite se n1 me ayega

    eduncle-logo-app

    yes sir maine shortest wavelength ke baare main socha hi ni

    eduncle-logo-app

    here n1 and n2 represent only levels

    eduncle-logo-app

    now got it?

    eduncle-logo-app

    yes sir

    eduncle-logo-app

    thanks

    yes shweta....

    eduncle-logo-app

    energy wavelength inverse relation

    eduncle-logo-app

    now check this quest.

    eduncle-logo-app

    yes Shweta??

    eduncle-logo-app

    for shortest wavelength energy is maximum

    eduncle-logo-app

    so here we take n1=1 and n2= infinity

    eduncle-logo-app

    sir

    eduncle-logo-app

    but energy to n2 -n1 ki jada

    eduncle-logo-app

    infinity kyin

    eduncle-logo-app

    haa jyada hogi tb na wavelength shortest hogi

    eduncle-logo-app

    fg

    eduncle-logo-app

    shweta shortest means sabse kam...to energy sabse jyada...to lyman series me n1=1 to hota hi hai

    eduncle-logo-app

    jb n2= infinity lenge to energy gap sabse jyada hoga

    eduncle-logo-app

    kha dikkat aa rhi hai Shweta??

    eduncle-logo-app

    main yhi Soch ri thi ki e2 - E1 ki energy sbse jada

    eduncle-logo-app

    nhi shweta yha or sabhi ke respect me sabse max energy dekhna hai

    eduncle-logo-app

    jo n1=1 to n2= infinity me hoga

    eduncle-logo-app

    mane shortest Dekha hi ni

    eduncle-logo-app

    sry sir

    eduncle-logo-app

    it's okay😊

    eduncle-logo-app

    now clear na..??

    eduncle-logo-app

    yes sir

    eduncle-logo-app

    😊👍

    eduncle-logo-app

    sir

    eduncle-logo-app

    yes shweta?
