Hertz (Hz), the unit of frequency, measures the number of cycles per second. It’s named after Heinrich Hertz, the physicist who first proved the existence of electromagnetic waves. In 1888, his groundbreaking experiments paved the way for the development of radio, television, and other communication technologies. Fascinatingly, the concept of frequency extends well beyond sound — it’s also crucial in physics, describing phenomena such as light waves and even the rotation of electron orbitals.

In our everyday lives, Hertz is everywhere. When you listen to music, the pitch you hear is influenced by the frequency in Hertz, with middle C on a piano vibrating at about 261.6 Hz. Even your household electrical system operates at frequencies of 50 or 60 Hz, depending on your region. This widespread influence underscores how integral Hertz is to both technology and daily experiences.

Did you know?

Terahertz, symbolized as THz, is a unit of frequency equivalent to one trillion cycles per second, or 1,000,000,000,000 Hz. In the electromagnetic spectrum, terahertz waves occupy the fascinating territory between microwaves and infrared light. This region, often referred to as the “terahertz gap,” has long captivated scientists because of its potential in numerous applications, including advanced imaging techniques, security screening, and even the detection of defects in materials.

Remarkably, terahertz radiation is non-ionizing, meaning it is much safer for biological tissues compared to X-rays. This capability opens doors to potentially revolutionary medical imaging and diagnostics opportunities without the risk of harmful radiation exposure. As researchers continue to explore this “hidden power,” the future holds exciting prospects for terahertz technology across a multitude of fields.
