Measuring Light and Electromagnetic Waves

A nanometre (nm) is a unit of length equal to one billionth of a metre (1 nm = 10⁻⁹ m) and is commonly used to express wavelengths of light and other electromagnetic waves. In this context, nanometres provide a convenient scale for describing phenomena that occur at the atomic and molecular level. Visible light, for example, spans wavelengths from about 380 nm (violet) to 750 nm (red). Ultraviolet (UV) light has shorter wavelengths, typically between 10 nm and 400 nm, while infrared (IR) light has longer wavelengths, from about 750 nm to 1,000,000 nm.

Wavelengths in nanometres are critical in fields like optics, photonics, spectroscopy, and nanotechnology. They determine the energy and color of light, how it interacts with matter, and how it can be manipulated in devices like lasers, fiber optics, and solar cells. Shorter wavelengths (in the UV or X-ray range) carry more energy and are used in applications such as medical imaging and semiconductor fabrication. Understanding and working with wavelengths in nanometres allows scientists and engineers to explore and control the behavior of light at extremely small scales—down to the size of atoms and molecules.

Frequencies in the Tens of Hertz

The dekahertz (daHz) is a unit of frequency equal to 10 hertz (10¹ Hz), meaning there are 10 cycles per second. This frequency range is significant in many fields, including acoustics, electronics, and communications, where oscillations occur in the lower audio and signal processing bands.

In acoustics, frequencies around dekahertz values fall within the lower range of human hearing, which spans roughly from 20 Hz to 20,000 Hz. Sounds at 10 Hz, though below typical hearing thresholds, can be felt as vibrations, especially in certain environments like heavy machinery or seismic activity.

In electronics and signal processing, dekahertz frequencies are important for analyzing signals such as low-frequency radio transmissions, audio signals, and mechanical vibrations. These frequencies are relevant for technologies like sonar, medical ultrasound imaging, and certain communication systems.

In addition, dekahertz frequencies play a role in studying natural phenomena, such as seismic waves and biological rhythms, where oscillations occur on the order of tenths of a second.

Understanding and utilizing dekahertz frequencies enables engineers and scientists to design devices and systems that interact with signals in the low-frequency audio and vibration ranges, bridging the gap between infrasonic and audible frequencies.
