Teaching UP PGT Mock Test Series 2024 Physical Sciences Electromagnetic Theory Electromagnetic Waves
The electric field and magnetic field components of an electromagnetic wave going through vacuum is described by
Ex = E0sin(kz − ωt)
By = B0sin(kz − ωt)
Then the correct relation between E0 and B0 is given by
1
E0 B0 = ωk
2
E0 = kB0
3
kE0 = ωB0
4
ωE0 = kB0
