The electric field part of an electromagnetic wave in a medium is represented by: {\E}_{ {\x}}=0 {\E}_{ {\y}}=2.5 { {\N}}/{ {\C}} \cos [(2 \pi \times 10^6 { {\rad}}/{ {\m}}) {\t}-(\pi \times 10^{-2} { {\rad}}/{ {\s}}) {\x}] {\E}_{ {\z}}=0. The wave is :

Correct Answer is : Moving along x direction with frequency 106 Hz and wavelength 200m

Moving along - {\x} direction with frequency 10^6 {\Hz} and wavelength 200 {\m}

Moving along y direction with frequency 2 \pi \times 10^6 {\Hz} and wavelength 200 {\m}

Moving along x direction with frequency 10^6 {\Hz} and wavelength 100 {\m}

Moving along x direction with frequency 10^6 {\Hz} and wavelength 200 {\m}
