It will be delivered in a case with the GOLD STONE logo. ◆Terahertz The secret to terahertz ore lies in the energy that causes molecular vibrations to occur one trillion times per second. Terahertz waves (tera/1 trillion hertz waves) emitted from terahertz ore are electromagnetic waves that fall between "light sources such as far-infrared rays" and "radio waves." These terahertz waves possess properties of both light and radio waves, with frequencies ranging from 1 trillion Hz to 100 trillion Hz and wavelengths from 3 μm to 1000 μm.
