hullámhosszúak

Hullámhosszúak is a Hungarian term that translates to "long-wavelength" in English. It is most commonly used in the context of radio waves, referring to electromagnetic radiation with relatively long wavelengths. These wavelengths are typically measured in meters or even kilometers, and correspond to low frequencies.

In the radio spectrum, long wavelengths are associated with very low frequency (VLF) and low frequency (LF) bands. These frequencies range from 3 kHz to 300 kHz. Due to their long wavelengths, these waves can travel long distances, particularly over water, and can penetrate obstacles like the Earth's surface to some extent. This makes them useful for specific applications where long-range communication is critical, such as submarine communication, navigation systems, and some forms of broadcasting.

The term "hullámhosszúak" can also be used more generally to describe any phenomenon characterized by long wavelengths, although its primary association remains with radio waves. Understanding the concept of wavelength is fundamental in physics and engineering, as it dictates the behavior and properties of waves, including their interaction with matter and their ability to propagate. The inverse relationship between wavelength and frequency is a key principle: longer wavelengths correspond to lower frequencies, and shorter wavelengths correspond to higher frequencies.
