Electromagnetic Wave Generation Matching
This solution details the matching between different electromagnetic waves (List-I) and their production mechanisms or sources (List-II), based on the provided correct answer.
A. Radio-wave matched with IV. due to rapid acceleration of electrons
Radio waves are generated by the acceleration of charged particles, typically electrons oscillating in an antenna. This process produces electromagnetic radiation in the radio frequency spectrum.
B. Micro-wave matched with III. due to change in the vibrational modes of atoms
According to the provided correct answer, microwaves are linked to the phenomenon of changes in the vibrational modes of atoms.
C. Infrared-wave matched with I. is produced by Magnetron valve
Based on the given correct matching, infrared waves are associated with production by a Magnetron valve.
D. X-ray matched with II. due to inner shell electrons moving from higher energy level to lower energy level
X-rays are characteristically produced when electrons transition from higher energy states to lower energy states within the inner electron shells of an atom, emitting high-energy photons.
