High-Frequency Waves in Communication and Technology

The megahertz (MHz) is a unit of frequency equal to 1,000,000 hertz (10⁶ Hz), representing one million cycles per second. Frequencies in the megahertz range are crucial in many modern technologies, especially in radio communications, broadcasting, and electronics.

In radio broadcasting, many AM and FM radio stations transmit signals in the MHz range. FM radio typically operates between 88 MHz and 108 MHz, providing high-quality audio signals for millions of listeners worldwide. Television broadcasting and two-way radio communications also use megahertz frequencies to transmit sound and images over long distances.

In electronics, MHz frequencies are key in the operation of microprocessors, oscillators, and wireless communication devices such as cell phones, Wi-Fi routers, and Bluetooth gadgets. The clock speed of many computer processors is measured in MHz (and GHz), determining how fast the processor can execute instructions.

Moreover, MHz frequencies are important in scientific instruments like radar systems and medical imaging devices, where high-frequency waves improve resolution and data accuracy.

Understanding and utilizing megahertz frequencies allows engineers to design efficient communication systems and advanced electronic devices that power today’s digital world.

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.
