Match the List-I with List-II

Choose the correct answer from the options given below:
(1) A-II,B-IV,C-III,D-I
(2) A-IV,B-III,C-I,D-II
(3) A-IV,B-I,C-II,D-III
(4) A-IV,B-II,C-I,D-III

Answer: A → IV, B → I, C → II, D → III

Solution

Radio waves are generated by the rapid acceleration of electrons in an antenna, which matches IV. Microwaves are produced by a magnetron valve, matching I. Infrared radiation arises from changes in the vibrational modes of atoms and molecules, matching II. X-rays are emitted when inner-shell electrons drop from higher to lower energy levels, matching III. The correct matching is A-IV, B-I, C-II, D-III.
