dispersioonijooni
Dispersioonijooni, known in English as dispersion lines or dispersion curves, are a fundamental concept in physics and engineering, particularly in the study of wave propagation. They graphically represent how the phase velocity or group velocity of a wave depends on its frequency or wavelength in a given medium. Essentially, a dispersion curve illustrates the phenomenon of dispersion, where different frequencies of a wave travel at different speeds.
The horizontal axis of a dispersion diagram typically represents frequency (often denoted by ω) or wavenumber (often
The analysis of dispersion curves is vital for understanding phenomena like the spreading of light pulses
