Electromagnetic Waves - Result Question 10

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

[2011]

(a) $[\vec{E} = E_{0} \hat{i}, \vec{B} = B_{0} \hat{j}]$

(b) $[\vec{E} = E_{0} \vec{k}, \vec{B} = B_{0} \hat{i}]$

(d) $[\vec{E} = E_{0} \hat{j}, \vec{B} = B_{0} \hat{k}]$

Show Answer

Answer:

Correct Answer: 10. (a)

Solution:

(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.
