When frequencies have been used for one purpose, perhaps for decades, it is often difficult to reallocate these frequencies for a different use. The need for reallocation - often known as re-farming - can arise in several ways.

Spectrum refarming refers to the process of reallocating or repurposing existing spectrum bands to improve efficiency and meet the increasing demand for wireless communication services. It involves modifying and optimizing the use of spectrum resources to better accommodate new technologies or services. Spectrum refarming can help maximize spectrum utilization and mitigate congestion in wireless networks.
The rainbow displays a spectrum of colors from red to violet.
We can see the visible spectrum of light, which ranges from violet to red. This spectrum includes all the colors of the rainbow.
Most stars exhibit a continuous spectrum, which contains all wavelengths of light in a continuous distribution. This is often referred to as a blackbody spectrum due to its smooth curve.
The main difference is in how they disperse light. A prism disperses light based on the material's refractive index, while a grating disperses light based on the wavelength of the light itself. This results in different patterns and resolutions in the spectra they produce.
