An electromagnetic wave travels in vacuum along z - direction : vec(E )=(E_(1)hat(i)+E_(2)hat(j))cos(kz-omega t). Choose the correct options from the following : |
|
Answer» The associated magnetic field is given as`vec(B)=(1)/(c )(E_(1)-E_(2)hat(j))cos (kz-omega t)` `vec(E )=(E_(1)hat(i)+E_(2)hat(j))cos (kz-omega t)` and Magnetic field vector, `vec(B)=(vec(E ))/(c )=((E_(1)hat(i)+E_(2)hat(j))cos (kz-omega t))/(c )` Thus,`vec(E )` and `vec(B)` propagate PERPENDICULAR to each other also perpendicular to DIRECTION of propagation. Hence electromagnetic WAVES is plane POLARIZED. |
