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.
