Electromagnetic Waves question

2023 · 24 Jan · Shift 2 · Q54

JEE MainPhysicsElectromagnetic WavesMCQ+4 / −1
The electric field and magnetic field components of an electromagnetic wave going through vacuum is described by Ex=Eosin⁡(kz−ωt)By=Bosin⁡(kz−ωt)\mathrm{{E_x} = {E_o}\sin (kz - \omega t)}\mathrm{{B_y} = {B_o}\sin (kz - \omega t)}Ex​=Eo​sin(kz−ωt)By​=Bo​sin(kz−ωt) Then the correct relation between E 0_00​ and B 0_00​ is given by
  1. A
    EoBo=ωk\mathrm{{E_o}{B_o} = \omega k}Eo​Bo​=ωk
  2. B
    E0=kB0\mathrm{{E_0} = k{B_0}}E0​=kB0​
  3. C
    kE0=ωB0\mathrm{k{E_0} = \omega {B_0}}kE0​=ωB0​
  4. D
    ωE0=kB0\mathrm{\omega {E_0} = k{B_0}}ωE0​=kB0​
