List of top Physics Questions on Electromagnetic waves asked in AMUEEE

An electromagnetic wave is propagating along $x-axis$. At $x = 1 \,m$ and $t = 10\, s$, its electric vector $| \vec{E} | = 6\, V/ m$ then the magnitude of its magnetic vector is

A plane electromagnetic wave of frequency $25 \,MHz$ travels in free space along the $x$-direction. At a particular point in space and time, $E=6.3 \hat{j} \,V / m$. At this point $B$ is equal to
