In this Ques C is given as a correct option …Par ye to galat hona chahiye…
As for diff elements characterstic lines are uniqe so it should be ‘must’
But it may be possible that difference in energy of any two levels in one kind of metal is equal to the difference in energy of any two different levels in another metal,then the wavelength of corresponding characteristic lines will remain same.
Bro but having the same wavelength and same charaterstic lines are two diff thing they can have the same wavelength but how possible they will have the same intensity…
And if the elements can have the same charasterstic lines then how they are “charasterstic”
Sonu already said what I said, so i deleted my reply.
what about my logic bro…
Yeah bro. After I read your logic I agree to that. Characteristic line compare karenge toh K alpha se K alpha hi karenge which is diff for diff metal.
Bol toh sahi rhe ho.
