Choose the correct answer from the options given below:
| List I (Spectral Lines of Hydrogen for transitions from) | List II (Wavelengths (nm)) | ||
| A. | to | I. | 410.2 |
| B. | to | II. | 434.1 |
| C. | to | III. | 656.3 |
| D. | to | IV. | 486.1 |
Show answer and solution
Answer: (b)
- Larger energy gap means shorter wavelength, so decreases as increases for the Balmer lines.
- (): 656.3 nm (III); (): 486.1 nm (IV)
- (): 434.1 nm (II); (): 410.2 nm (I)
- So the answer is (b) A-III, B-IV, C-II, D-I.
