Question

In an electromagnetic wave,
$1$. electric field and magnetic field are parallel to each other.
$2$. electric field and magnetic field are perpendicular to each other.
$3$. electric field and magnetic field both are perpendicular to direction of propagation of wave.

• A. $1$ and $2$
• B. All are correct
• C. Only $2$
• D. $2$ and $3$

Answer 1

The correct option is D $2$ and $3$

In EM waves, Electric and Magnetic fields oscillate perpendicular to each other and to the direction of wave-propagation.

So statements 2 and 3 are correct.

Option D is correct.
