JEE Main 2026 — 24 January, Morning Shift — Question 33

Match the List-I with List-II

List-I	List-II
A. Radio-wave	I. is produced by Magnetron value
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 energy level to lower energy level
D. X-ray	IV. Due to rapid acceleration of electrons

Choose the correct answer from the options given below:

Option A:
$A-II,B-IV,C-III,D-I$
Option B:
$A-IV,B-III,C-I,D-II$
Option C:
$A-IV,B-I,C-II,D-III$
Correct
Option D:
$A-IV,B-II,C-I,D-III$

Answer: C

Step-by-step solution

Radio wave ⇒ Produced by rapid acceleration of electrons Micro wave ⇒ By magnetron valve Infrared wave ⇒ Change in vibrational modes X ray ⇒ Transition of inner shell electrons from high energy level to low energy level. A - IV, B - I, C - II, D - III
