Solution

## The correct option is C (I - R, U), (II - S, U), (III - P, U), (IV - Q, U)(I) For Lyman series, ¯v for second line (3→1)=R(1)2[112−132]=8R9 (II) For Balmer series, ¯v for second line 4→2=R(1)2[122−142]=3R16 (III) In a sample of H-atom for 5→2 transition, maximum number of spectral lines observed =(5−2)(5−2+1)2=6 (IV) In a single isolated H-atom for 3→1 transition, maximum number of spectral lines observed =2(3→2,2→1)
