|---|---|
| A. Microwave | I. Electrons in atoms emit light when they move from a higher energy level to a lower energy level |
| B. Visible light | II. Radioactive decay of nucleus |
| C. Gamma rays | III. Vibration of atoms and molecules |

Choose thecorrectanswer from the options given below :NEET 2026 (Cancelled)
Options:
Answer:
Solution:
Microwaves are produced by special vacuum tubes such as klystron valves, magnetron valves, and Gunn diodes. Thus, A matches IV.
Visible light is produced when electrons in atoms undergo transitions from a higher energy level to a lower energy level. Thus, B matches I.
Gamma rays are produced during the radioactive decay of the nucleus and other nuclear reactions. Thus, C matches II.
Infra-red rays are produced by hot bodies and molecules, specifically due to the vibration of atoms and molecules. Thus, D matches III.
The correct matching is A-IV, B-I, C-II, D-III.
Answer: A-IV, B-I, C-II, D-III
