Properties of EM Waves: Practice Problem & Solution
Match column I with column II. | Column-I (Types of EM waves) | Column-II (Production) | | A. Infra-red | P. Rapid vibration of electrons in aerials | | B. Radio | Q. Electrons in atoms emit light when they move from higher to lower energy level. | | C. Light | R. Klystron valve | | D. Microwave | S. Vibration of atoms and molecules | Choose the correct match from the options given below:
Solution Explained:
To solve this problem, we apply the core principles of Properties of EM Waves. Understanding the underlying formula is key to arriving at the correct answer below:
Infrared waves are produced by molecular vibrations (A-S). Radio waves by accelerating charges in aerials (B-P). Light waves by atomic transitions (C-Q). Microwaves by klystron/magnetron valves (D-R).
