MHz antenna carried by an airplane flying over the ocean surface generates a wave that approaches the water surface in the form of a normally incident plane wave with an electric-field amplitude of 5500 VIm. Seawater is characterized by a dielectric constant of 72, relative permeabity of 1 and conductivity of 4 Sim. The plane is trying to communicate a message to a submarine submerged at a depth d below the water surface. If the submarine's receiver requires a minimum signal amplitude of 0.03 u Vim), what is the maximum depth d to which successful communication is still possible? Answer-
