NEET Physics Maxwell's Equations MCQ Question

Type: MCQ-diagram based-Hard-Class 12

In the diagram shown above, which equation correctly expresses the relationship between the speed of light cc, the angular frequency ω\omega, and the wave vector kk for electromagnetic waves?

Question diagram
A

c=ω/kc = \omega / k

B

c=k/ωc = k / \omega

C

c=ω×kc = \omega \times k

D

c=ω+kc = \omega + k

Correct Answer

Option A

Detailed Explanation

According to the NCERT, the speed of an electromagnetic wave is given by the relation c=ω/kc = \omega / k, where ω\omega is the angular frequency and kk is the wave vector.
