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

For which of the following media will the wave propagation occur without experiencing attenuation?

The speed of electromagnetic waves is the same for all ........

$A$ light wave traveling in air along the $x$-direction is given by $E_{y} = 540 \sin \pi \times 10^{4}(x - ct) \text{ Vm}^{-1}$. Then,the peak value of the magnetic field of the wave will be $\dots \times 10^{-7} \text{ T}$ (Given $c = 3 \times 10^{8} \text{ ms}^{-1}$)

The dielectric constant of a medium is $8$ and its relative permeability is $200$. If an electromagnetic wave of frequency $100 \text{ MHz}$ travels in this medium,then its wavelength is

Atmospheric conditions affect ......... space waves.
