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 xx 10^(6) ((rad))/((s))) t-left(pi xx10^(-2) . ((rad))/((m))) x]``E_(z)=0` If the wave is moving along `x` -direction with frequency `x` hertz and its wavelength is `y` metres, then find `(x)/(y)`.
