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 isA. 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. |
