Is a fluorescent light a continuous spectrum
Web26 nov. 2024 · Continuous spectrum is mainly produced by thermal emission from a blackbody. Only certain wavelengths can be emitted and absorbed by the atom when the energy levels in the atom are quantized. This can be explained by Bohr’s Quantization Principle.

WebAccording to Kirchoff’s third law, when a hot, opaque object (or any other source of a continuous spectrum) lies behind a cool, low-density gas, dark absorption lines appear in the otherwise continuous spectrum. This occurs in nearly every star, since light from the interior must pass through the cooler, outer layers. Web8 sep. 2024 · As an example, consider the spectrum of sunlight shown in Figure \(\PageIndex{7}\) Because the sun is very hot, the light it emits is in the form of a continuous emission spectrum. Superimposed on it, however, is a series of dark lines due primarily to the absorption of specific frequencies of light by cooler atoms in the outer …
WebIf the rainbow that is produced has all the colors from red to violet, and has no gaps between them, then it is referred to as a continuous spectrum.

Although fluorescent light approximates natural, white light, the spectrum of a fluorescent light is not the continuous spectrumof an incandescent light. … The incandescent light gives a continuous spectrum, while the fluorescent light gives discrete lines typical of the …
Web12 aug. 2024 · The most common example for a continuous spectrum is the spectrum of light emitted by excited atoms of hydrogen. This spectrum is created due to free electrons, which become bound to a hydrogen ion and emit photons that tend to smoothly spread over a wide range of wavelengths.

WebA deuterium lamp requires a large and complex power supply, making it more expensive than a halogen lamp. However, it is one of the few continuous spectrum light sources that is stable in the ultraviolet range. The deuterium lamp has a short emission wavelength of 400 nm, or less. The window material limits its use at the short wavelength end. ty73rWeb1 sep. 2012 · Although fluorescent light approximates natural, white light, the spectrum of a fluorescent light is not the continuous spectrum of an incandescent light.
