The Unit of Frequency

The term cycle per second, commonly known as the hertz (Hz), is the standard unit of frequency in the International System of Units (SI). It measures how many complete cycles or oscillations of a periodic event occur in one second. For example, if a wave oscillates 60 times in one second, it has a frequency of 60 Hz. The concept of cycle per second applies to many fields including sound waves, electromagnetic waves, mechanical vibrations, and alternating current electricity.

Frequency determines many important characteristics of waves, such as pitch in sound or color in light. In electrical engineering, frequency dictates the behavior of AC power systems, with the standard mains electricity frequency being 50 or 60 Hz depending on the country. Radio and television broadcasts also rely on specific frequencies to transmit signals.

Using cycle per second as a unit helps scientists and engineers understand and quantify periodic phenomena. The hertz is essential for designing electronic devices, communication systems, and studying natural oscillations. It provides a universal language to describe the repetitive nature of waves and signals, enabling consistent measurement and comparison across different scientific disciplines.

The Vastest Scales of Cosmic Waves

An exametre (Em) is equal to 1,000 petametres (10¹⁸ metres), representing one of the largest units of length used to describe the longest electromagnetic wavelengths and gravitational waves in the universe. At this scale, wavelengths correspond to frequencies in the zeptohertz (10⁻²¹ Hz) range and lower, which are incredibly slow oscillations occurring over billions of years and spanning distances larger than entire galaxy superclusters.

For example, waves with a frequency of around 1 zeptohertz have wavelengths on the order of 300 exametres. These enormous waves are primarily theoretical and are significant in cosmology and astrophysics for studying the large-scale structure of the universe, primordial fluctuations from the Big Bang, and the behavior of space-time itself.

Using exametres to express wavelength helps scientists conceptualize the almost incomprehensible vastness of the cosmos. These extreme wavelengths provide key insights into the fundamental nature of the universe, including gravitational wave backgrounds and the evolution of cosmic structures on the grandest scales.
