Match each List-I with an appropriate pair of characteristics from List-II and select the correct answer using the code given below the lists.
List-I | List-II | ||
P | Lyman series | 1 | maximum number of spectral line observed = 6 |
Q | Balmer series | 2 | maximum number of spectral line observed = 2 |
R | In a sample of H-atom for 5 upto 2 transition. | 3 | 2nd line has wave number |
S | In a single isolated H-atom for 3 upto1 transition. | 4 | 2nd line has wave number |
P Q R S

Verified by ExpertsCHECK THE SOLUTION.
P : For Lyman series, 
for second line (3 → 1) = R(a) 2 
= 
.
Q : For Balmer series, 
for second line (4 → 2) = R(a) 2 
= 
.
R : In a sample of H-atom for 5 → 2 transition, maximum number of spectral lines observed
= 
= 6 .
S : In a single isolated H-atom for 3 → 1 transition, maximum number of spectral lines observed = 2 (3 → 2, 2 → 1)
