A sound whistle blowing system is a critical component of good corporate governance. While public companies are required to meet SOX whiste blowing standards, private organizations, as well as small businesses, have also followed suit.
Previous answer: 1,729 MHz. There is no resonant frequency of gold. Gold does have an NMR frequency, which is 1.729MHz. All NMR frequencies are dependent on the ambient magnetic field, and gold's 1.729MHz is valid for a magnetic field of 2.35 Teslas, which is 45,000 times stronger than a typical Earth field strength.
Gold. Gold is a poor insulator and a good conductor, having a resistivity of 22.4 billionths of an ohm-meter. As with lead, gold is widely used to make electronic contacts. Unlike many other metals, it is very chemically stable and resists the corrosion that degrades other types of electrical connectors.
