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 `overline(B) = (1)/(C ) (E_(1) hat(i) + E_(2) hat(j)) cos (kz - omega t)`

B

The associated magnetic field is given as `overline(B) = (1)/(C ) (E_(1) hat(i) - E_(2) hat(j)) cos (kz - omega t)`

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 )`
`overline(B) = (E )/(C ) = (1)/(C ) (E_(1) hat(i) + E_(2) hat(j)) cos (kz - omega t)`
