An e.m. wave travels in vacuum along z direction:
`vecE=(E_1hati+E_2hatj)cos (kz-omega)`. Choose the correct option from the following :

A

The associated magnetic field is given as `vecB=1/C(E_(1)hati+E_(2)hatj)cos(kz-omegat)`

B

The associated magnetic field is given as`vecB=1/C(E_(1)hati-E_(2)hatj)cos(kz-omegat)`

C

The given electromagnetic field is circularly polarised

D

The given electromagnetic field is not plane polarised

Text Solution

Verified by Experts

The correct Answer is:
A
`C=(E)/(B)," "B=(E)/(C)`
`vecB=(vecE)/(C)=(1)/(C)(E_(1)hati+E_(2)hatj)cos(kz-omegat)`
