Question:medium

A magnetic field vector in an electromagnetic wave is represented by
$\vec{B} = B_0 \sin \left( 2\pi \nu t - \frac{2\pi x}{\lambda} \right) \hat{j}$. Its associated electric field vector is _______.

Updated On: Apr 10, 2026

$\vec{E} = -v \lambda B_0 \sin\left(2\pi\nu t - \frac{2\pi x}{\lambda}\right) \hat{k}$
$\vec{E} = -v \lambda B_0 \sin\left(2\pi\nu t - \frac{2\pi x}{\lambda}\right) \hat{i}$
$\vec{E} = v \lambda B_0 \sin\left(2\pi\nu t - \frac{2\pi x}{\lambda}\right) \hat{k}$
$\vec{E} = v \lambda B_0 \sin\left(2\pi\nu t - \frac{2\pi x}{\lambda}\right) \hat{i}$

Statement I: Since fluorine is more electronegative than nitrogen, the net dipole moment of NF₃ is greater than NH₃.
Statement II: In NH₃, the orbital dipole due to the lone pair and the dipole moment of NH bonds are in opposite directions, but in NF₃, the orbital dipole due to the lone pair and the dipole moments of N-F bonds are in the same direction.
In light of the above statements, choose the most appropriate from the options given below:
