The electric and the magnetic field, associated with an e.m. wave propagating along the `+z`axis, can be represented by

A

`[vecE=E_(0)hati, vecB=B_(0)hatj]`

B

`[vecE=E_(0)veck,vecB=B_(0)hati]`

C

`[vecE=E_(0)hatj,vecB=B_(0)hati]`

D

`[vecE=E_(0)hatj, vecB=B_(0)hatk]`

Text Solution

Verified by Experts

The correct Answer is:
A
E.M. wave always propagates in a direction perpendicular to both electric and magnetic fields. So, electric and magnetic fields should be along `+X-` and `+Y-` directions respectively. Therefore, option (a) is the correct option.
