JEE Main 2023 — Electromagnetic Waves Question with Solution

JEE Main 2023 (24 Jan Shift 2)

Question

The electric field and magnetic field components of an electromagnetic wave going through vacuum is described by

 Ex=E0sinkz-ωt

By=B0sinkz-ωt

Then the correct relation between E0 and B0 is given by 

Choose an option

Show full solutionCorrect option: C
Correct answer
CkE0=ωB0

Step-by-step explanation

As we know, electric field and magnetic field are related as 

E0=cB0, where, c is speed of light in vacuum

Also c=ωk

⇒E0=ωkB0

⇒  E0k=ωB0
