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}} ) {x} - (\\pi\\times10^{-2} { {\rad}}/{ {\s}} ) {t} ] ; {\E}_{ {z}}=0 . The wave is :-

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

Moving along –x direction with frequency 10^{6} Hz and wave length 200 m

Moving along y direction with frequency 2π × 10^{6} Hz and wave length 200 m

Moving along x direction with frequency 10^{6} Hz and wave length 100 m

Moving along x direction with frequency 10^{6} Hz and wave length 200 m
