NEET 2026 Physics question
Match List I with List II: List-I (Electromagnetic wave) A. Microwave B. Visible light C. Gamma rays D. Infra-red rays List-II (Production) I. Electrons in atoms emit light when they move from a higher energy level to a lower energy level II. Radioactive decay of nucleus III. Vibration of atoms and molecules IV. Klystron valve or magnetron valve Choose the **correct** answer from the options given below:
Solution
Microwaves are produced by special vacuum tubes such as klystron and magnetron valves (A-IV). Visible light is emitted when atomic electrons drop from a higher to a lower energy level (B-I). Gamma rays arise from radioactive decay of nuclei (C-II). Infra-red
