Answer & Solution
Correct Answer
(D) (A), (B) and (C) only
Step-by-step Solution
Detailed explanation
Statements A, B, and C are fundamental properties of electromagnetic waves, describing their transverse nature, ionospheric reflection for communication, and identical oscillation frequencies. While Ampere's Law exists, Statement D is not considered a defining characteristic of…
