NettetA spectral lineis a weaker or stronger region in an otherwise uniform and continuous spectrum, resulting from emissionor absorptionof lightin a narrow frequencyrange, compared with the nearby frequencies. Spectral lines are … NettetIn the physical sciences, the spectrum of physical quantity (such as energy) may be called continuous if it is non-zero over the whole spectrum domain (such as frequency or …

Photons emitted from the core of a star contain all the wavelengths and frequencies of the electromagnetic spectrum This is called a continuous spectrum; Continuous spectra are produced from hot, dense sources, such as the cores of stars; A continuous spectrum is one which emits all wavelengths of light minerals supplier in banswara

Spectral line - Wikipedia

NettetLine spectra were first observed and studied in the latter half of the 19th century, but it was only in the 1920s that a full explanation was finally developed. To explain the … Nettet11. apr. 2024 · The light from an astronomical source can consist of a continuous spectrum, an emission (bright line) spectrum, or an absorption (dark line) spectrum. Because each element leaves its spectral signature in the pattern of lines we observe, spectral analyses reveal the composition of the Sun and stars. Glossary absorption … NettetLine Spectra. Line spectra is a phenomenon which occurs when excited atoms emit light of certain wavelengths which correspond to different colours. The emitted light can be observed as a series of coloured lines with dark spaces in between. These series of coloured lines are called line or atomic spectra. Each element produces a unique set … mineral starting with b
