Megahertz (MHz) is a common unit of frequency that represents one million cycles per second and is particularly known for its vital role in telecommunications and computing. The term hertz pays homage to Heinrich Hertz, the first person to conclusively prove the existence of electromagnetic waves. In radio broadcasting, the station dial numbers you tune into represent megahertz, which indicate the carrier frequency of the radio station. For example, a frequency of 101.1 MHz means the wave completes 101.1 million cycles every second!

In computing, the speed of the early personal computers was often measured in megahertz. Though we’ve progressed to gigahertz in modern-day processors, the megahertz era marked some groundbreaking advancements in technology. The original IBM PC, introduced in 1981, had a processor speed of just 4.77 MHz. Today, such performance pales in comparison, revealing the incredible strides in processing power over the decades.

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.
