Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Radio-waves (A).
Radio-waves are produced due to rapid acceleration of electrons in transmitting antennas.
Hence, A $\rightarrow$ IV.
Step 2: Micro-waves (B).
Micro-waves are generated using a magnetron valve.
Hence, B $\rightarrow$ II.
Step 3: Infrared-waves (C).
Infrared radiation is mainly produced due to vibrational motion of atoms and molecules.
Hence, C $\rightarrow$ I.
Step 4: X-rays (D).
X-rays are produced due to inner shell electronic transitions.
Hence, D $\rightarrow$ III.
Step 5: Final conclusion.
The correct matching is A-IV, B-II, C-I, D-III, corresponding to option (1).
