JEE Mains · Physics · STD 12 - 8. Electromagnetic waves
The electric field and magnetic field components of an electromagnetic wave going through vacuum is described by \(E _{ x }= E _0 \sin ( kz -\omega t )\) \(B _{ y }= B _0 \sin ( kz -\omega t )\) Then the correct relation between \(E_0\) and \(B_0\) is given by
- A \(kE _0=\omega B _0\)
- B \(E _0 B _0=\omega k\)
- C \(\omega E _0= kB _0\)
- D \(E _0= kB _0\)
Answer & Solution
Correct Answer
(A) \(kE _0=\omega B _0\)
