Spectral resolution refers to the ability of a measurement system, such as a spectrometer, to resolve features in the electromagnetic spectrum, distinguishing between closely spaced wavelengths or frequencies. Higher spectral resolution allows for more detailed analysis of the spectral characteristics of a sample, which is crucial in applications like remote sensing, astronomy, and material analysis.

A spectrometer is an analytical instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used to identify materials and analyze their composition. It works by dispersing light into its component wavelengths, allowing for detailed analysis of the spectral characteristics of a sample.

Frequencies refer to the rate at which a repeating event occurs over a specified period, typically measured in hertz (Hz), indicating cycles per second. This concept is prevalent in various fields like physics, where it describes wave behaviors, and in data analysis, where it reflects the periodicity of events or values.

Remote sensing is the acquisition of information about an object or phenomenon without making physical contact, typically through satellite or aerial imagery. It plays a critical role in environmental monitoring, disaster management, and resource exploration by providing valuable data on Earth's surface and atmosphere.

remote sensing

Astronomy is the scientific study of celestial objects, space, and the universe as a whole, aiming to understand their origins, evolution, and fundamental processes. It combines observational techniques with theoretical modeling to explore phenomena ranging from planets and stars to galaxies and cosmic microwave background radiation.
