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 y direction with frequency `2pixx10^(6)Hz` and wavelength 200 m.

B

moving along x direction with frequency `10^(6)Hz` and wavelength 100 m.

C

moving along x direction with frequency `10^(6)Hz` and wavelength 200 m.

D

moving along `-x` direction with frequency `10^(6)Hz` and wavelength 200 m.
