Tuning fork S - 250.56 Hz Schumann Resonance

Standing waves along the Earth's circumference

Schumann resonances are electromagnetic waves excited by lightning along the Earth's circumference. The poorly conductive earth surface (mostly salt water) and the highly conductive ionosphere above delimit a cavity resonator, from the dimensions of which possible resonance frequencies can be calculated. Waves that are in the same phase again after orbiting the earth (or the earth's circumference is an integer multiple of the wavelength) are amplified, others are canceled out.

This results in an average resonance frequency of 7.83 Hz. Five octaves higher is the frequency of the Schumann Resonance, a tone of 250.56 Hz. The octave correspondence in the light spectrum is the color yellow-green.

Tuning fork length: 16.1 cm
