The electric field part of an electromagnetic wave in a medium is represented by
`E_(x)=0,`
`E_(y)=2.5(N)/(C) cos[(2pixx10^(6)(rad)/(m))t-(pixx10^(-2)(rad)/(s))x]`
`E_(z)=0`.
The wave is

A

Moving along – x direction with frequency `2 pixx10^(6)` Hz and wave lengthh 200 m.

B

Moving along y direction with frequency `2pi xx 10^(6)` Hz and wave length 200 m.

C

Moving along x direction with frequency `10^(6)` Hz and wave length 100 m.

D

Moving along x direction with frequency `10^(6)` Hz and wave length 200 m.
