Sir question 8 ma ap na batia tha ka agr koi line n= 5 ma ati ha tu us ki wavelength highest hu although us ma kitna difference ha tu us ka according is ka answer b huna chayea but answer is ma d ha or dot solver na bi yahi answer di ha

D is correct bcz dekhy wha emission ka poucha gya ha jab k option B or C me to absorption ho rhi ha ha to wo nikl gay peechy bachy option D or A ab dekhy option A me qareeb waly shell se energy emit kar k aa rha ha or option D me door se aa rha ha sir n lecture me btaya tha jitna qareeb se emit kary ga utni wavelength zida ho gi or jitna door hota jay ga utni wavelength kam so us n highest wavelength pouchi ha energy or wavelength inversely proprotional hoty ha so option D is best for highest wavelength as it has low energy

Iska simple jawab ye hai ke question mein Emission pucha gaya hai, toh Options B aur C toh pehle hi race se bahar ho gaye kyunke wo Absorption (neeche se oopar jana) hain. Ab bache Options A aur D. Hamein pata hai ke highest wavelength ka matlab hota hai sab se kam energy Lyman series (2 -1) mein energy gap buhat zyada hota hai, jabke Balmer series (5 - 2) mein energy gap kam hota hai. Chunke 5 -2 transition ki energy sab se kam hai, isliye iski wavelength sab se zyada hogi, yani Option D sahi hai.

well explained abdullah

b main low se high ja raha hai so wo absorption spectrum hai. question main emissin required hai
