Hullámsugárhossz

Hullámsugárhossz is a Hungarian term that translates to "wave propagation length" or more commonly, "wavelength" in English. It is a fundamental concept in physics, particularly in wave phenomena such as light, sound, and electromagnetic radiation. The wavelength refers to the spatial period of a wave, meaning the distance over which the wave's shape repeats. It is the distance between two successive corresponding points of the same phase on the wave, such as two crests or two troughs.

The hullámsugárhossz is typically denoted by the Greek letter lambda ($\lambda$). It is inversely proportional to the frequency ($f$) of the wave and directly proportional to the speed ($v$) at which the wave propagates. This relationship is expressed by the equation $\lambda = v/f$. For example, in a vacuum, electromagnetic waves travel at the speed of light ($c$), so their wavelength is given by $\lambda = c/f$. Different wavelengths of light are perceived as different colors, while different wavelengths of sound are perceived as different pitches. Understanding hullámsugárhossz is crucial for various scientific and technological applications, including spectroscopy, telecommunications, and medical imaging.
