Did You Know?
The Schumann resonance — Earth's electromagnetic 'heartbeat' caused by lightning strikes — oscillates at about 7.83 Hz. Some researchers have claimed links to human brain alpha waves, though evidence is limited.
Ultrasound machines use frequencies between 2 and 18 MHz. At these frequencies, wavelengths in tissue are less than 1 mm, enabling detailed medical imaging.
A typical modern CPU runs at 3–5 GHz, completing 3–5 billion transistor switching cycles per second. In 1971, the first Intel 4004 processor ran at just 740 kHz.
The visible light spectrum spans roughly 430–770 THz (terahertz). Violet light vibrates almost twice as fast as red light — which is why violet bends more in a prism.
