spektriheijastus

Spektriheijastus, also known as spectral shift or spectral displacement, is a phenomenon in physics and engineering where the frequency of a wave changes due to interaction with a medium. This effect is commonly observed in optics, acoustics, and other wave-based systems. In optics, for example, spectriheijastus can occur when light passes through a medium with varying refractive index, such as a prism or a diffraction grating. The change in frequency is proportional to the change in the medium's properties, leading to a shift in the wavelength of the light. This principle is fundamental in various applications, including spectroscopy, where it is used to analyze the composition of materials, and in telecommunications, where it is employed in wavelength division multiplexing to transmit multiple signals simultaneously over a single optical fiber. Understanding spectriheijastus is crucial for designing and optimizing systems that rely on wave propagation and interaction.
