The electric field intensity of a linearly polarized uniform plane wave propagating in the +z direction in seawater is E= 100 cos(10^(7) pi*t) V/m at z = 0.
constant of emissivity = 8.854 * 10^(-12) F/m
mu(0) = 4*pi * 10^(-7) H/m
Er = 72
mu(r) = 1
phi = 4 s/m

b. determine the attenuation constant alpha.
c. determine the pase constant beta.
d. determine the phase velocity V.
