The Electric And Magnetic Field Associated With An Em Wave Physics Question

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

Options

(a) [ E = E₀i, B = B₀j ]
(b) [E = E₀k, B = B₀j ]
(c) [E = E₀j, B = B₀i ]
(d) [E = E₀j, B = B₀k ]

Correct Answer:

[E = E₀i, B = B₀j]

Explanation:

E.M. waves 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.
