Project Seafarer was an ambitious program to construct an enormous antenna, buried underground on a site about 10000 km2 in area. Its reason was to transmit signals to submarines while they were deeply submerged. Ordinarily, electromagnetic radiations do not penetrate very far into conductors such as seawater. Suppose that the effective wavelength was 3.4*104 Earth radii.

a) What would be the frequency of the radiations emitted?

b) What would be the period of the radiations emitted?
