Physics-Maxwell's Equations

NEET Physics Maxwell's Equations MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Which of the following statements about Maxwell's equations and electromagnetic waves are correct?

A

Maxwell's equations show that electric and magnetic fields can exist independently of each other.

B

The speed of electromagnetic waves is determined by the properties of the medium they travel through.

C

Displacement current contributes to the generation of magnetic fields in regions where electric fields change over time.

D

The relation ω = ck indicates that the frequency of electromagnetic waves is independent of their wavelength.

Correct Answer

Option C

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.
