A liquid with a real dielectric constant of 1.30 has sufficient ions dissolved in it to acquire a conductivity of 0.30

Siemens/m.

a) Is this liquid a "good conductor" for 5 Mhz radio waves? Justify your answer.

b) What fraction of the intensity of a perpendicularly incident plane wave at this frequency is transmitted ?

c) Immediately inside the surface, what is the electric field amplitude relative to the amplitude of the incident wave?

At what depth does the transmitted wave decrease in amplitude by 1/e?
