Choose the correct answer from the options given below:
(
| List-I | List-II | ||
| A. | Radio-wave | I. | is produced by Magnetron valve |
| B. | Micro-wave | II. | due to change in the vibrational modes of atoms |
| C. | Infrared-wave | III. | due to inner shell electrons moving from higher to lower energy level |
| D. | X-ray | IV. | due to rapid acceleration of electrons |
Choose the correct answer from the options given below:
Options
- AA-IV, B-II, C-I, D-III
- BA-IV, B-I, C-II, D-III
- CA-IV, B-III, C-I, D-II
- DA-II, B-IV, C-III, D-I
Correct answer
B. A-IV, B-I, C-II, D-III
Step-by-step solution
Matching electromagnetic wave sources:
Radio-wave (A) - produced by rapid acceleration of electrons in antennas and transmitters, matches IV.
Micro-wave (B) - produced by Magnetron valve, matches I.
Infrared-wave (C) - due to change in vibrational modes of atoms and molecules, matches II.
X-ray (D) - due to inner shell electrons moving from higher to lower energy levels, matches III.
Correct pairing: A-IV, B-I, C-II, D-III
