Question
2 Project Seafarer was an ambitious program to construct an
enormous antenna, buried underground on a site about 10 000 km²
in area. Its purpose was to transmit signals to submarines while they
were deeply submerged. If the effective wavelength were 1.0 × 104
Earth radii, what would be the (a) frequency and (b) period of the
radiations emitted? Ordinarily, electromagnetic radiations do not
penetrate very far into conductors such as seawater, and so normal
signals cannot reach the submarines.
