JEE Mains · Physics · STD 12 - 8. Electromagnetic waves
In an electromagnetic wave the electric field vector and magnetic field vector are given as \(\vec{E}=E_{0} \hat{i}\) and \(\vec{B}=B_{0} \hat{k}\) respectively. The direction of propagation of electromagnetic wave is along.
- A \(\hat{j}\)
- B \((\hat{k})\)
- C \((-\hat{k})\)
- D \((-\hat{j})\)
Answer & Solution
Correct Answer
(D) \((-\hat{j})\)
Step-by-step Solution
Detailed explanation
Direct of propagation \(=\vec{E} \times \vec{B}=\hat{i} \times \hat{k}=-\hat{j}\)
