The transverse nature of electromagnetic waves is demonstrated by which of the following phenomena?

$A$ plane electromagnetic wave propagating along the y-direction can have the following pair of electric field $(\vec{E})$ and magnetic field $(\vec{B})$ components.

$A$ radio receiver antenna that is $2 \, m$ long is oriented along the direction of the electromagnetic wave and receives a signal of intensity $5 \times 10^{-16} \, W/m^2$. The maximum instantaneous potential difference across the two ends of the antenna is

If $\overrightarrow E$ and $\overrightarrow B$ are the electric and magnetic field vectors of electromagnetic waves,then the direction of propagation of the electromagnetic wave is along the direction of:

When an $EM$ wave propagates through a vacuum,then:

In a plane electromagnetic wave,the electric field oscillates sinusoidally at a frequency of $2 \times 10^{10} \, Hz$ and an amplitude of $48 \, V/m$. What is the wavelength of the wave in $cm$?
