NEET Physics Maxwell's Equations MCQ Question
Which of the following statements about Maxwell's equations and electromagnetic waves are correct?
Maxwell's equations show that electric and magnetic fields can exist independently of each other.
The speed of electromagnetic waves is determined by the properties of the medium they travel through.
Displacement current contributes to the generation of magnetic fields in regions where electric fields change over time.
The relation ω = ck indicates that the frequency of electromagnetic waves is independent of their wavelength.
Correct Answer
Detailed Explanation
Statement C is correct as it highlights the role of displacement current in generating magnetic fields from changing electric fields, a key insight from Maxwell's equations. Statements A and D are incorrect because electric and magnetic fields are interdependent, and ω = ck implies a direct relationship between frequency and wavelength. Statement B, while partially correct, does not reflect the context of the question focusing on Maxwell's equations specifically.
