If a right-handed circularly polarized wave is incident normally on a plane perfect conductor, then the reflected wave will be

The electric field of a uniform plane electromagnetic wave is $$$\vec E = \left( {{{\overrightarrow a }_x} + j4{{\overrightarrow a }_y}} \right)\exp \left[ {j\left( {2\pi \times {{10}^7}t - 0.2z} \right)} \right]$$$

The polarization of the wave is

The electric field component of a plane wave traveling in a lossless dielectric medium is given by $$$\overrightarrow E \left( {z,t} \right) = {\widehat a_y}2\cos \left( {{{10}^8}t - {z \over {\sqrt 2 }}} \right)V/m.$$$

The wavelength )in m) for the wave is

Which one of the following field patterns represents a TEM wave traveling in the positive $$x$$ direction?
