Wireless Communications/submarine Communication


how submarine communication is happening?
(because salt water is conducting and electric field is inside a conductor is zero and so the wave could not penetrate that's why iam asking)

You are correct in stating that radio waves do not penetrate electrical conductors well.
That makes conventional wireless communications with submerged submarines impossible.  
However, RF waves do penetrate imperfect conductors somewhat, a phenomenon called "skin depth" and the effect is more pronounced as frequency rises.  At very long wavelengths useful signal remains meters under the surface of the sea and that permits some slow data communication with submerged vessels.
