Question

An electromognetic wave travels in vacuum along z direction: E=(E₁i+E₂j)cos(kz −ωt).Choose the correct options from the following:

(a) The associated magnetic field is given as

B=1/C(E₁i-E₂j)cos(kz −ωt).

(b) The associated magnetic field is given as

B=1/C(E₁i-E₂j)cos(kz −ωt).

(c) The given electromagnetic field is circularly polarised.

(d) The given electromagnetic wave is plane polarised.

Answer 1

(a), (d)

(a) The associated magnetic field is given as

B=1/C(E₁i-E₂j)cos(kz −ωt).

(d) The given electromagnetic wave is plane polarised.

Answer 2

It is given that E=(E₁i+E₂j)cos(kz −ωt)

In EM wave that associate magnetic field vector B=1/C(E₁i-E₂j)cos(kz −ωt) option a is true

Also E

and B are perpendicular to each other and the propagation of EM wave is perpendicular to E as well as B

The given electromagnetic wave is plane polarized.

option (a), (d) both are correct

(a) The associated magnetic field is given as

B=1/C(E₁i-E₂j)cos(kz −ωt).

(d) The given electromagnetic wave is plane polarized.
