Phosphorescent light emission occurs when a material absorbs and stores energy from a light source, then slowly releases it over time. Bioluminescent light emission, on the other hand, is produced by living organisms through a chemical reaction within their bodies.
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.
Bioluminescence is the production of light by living organisms, while phosphorescence is the emission of light by a substance after it has absorbed energy.
The Raman effect is the inelastic scattering of light by molecules, resulting in a shift in wavelength. Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Both phenomena involve interactions between light and molecules but differ in the mechanism of light emission.
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.
Helium has more emission lines than hydrogen because it has more electrons and energy levels, leading to more possible transitions between these levels and the emission of different wavelengths of light.
i have no idea do you he he shame whoever wanted this
Phosphorescent materials continue to emit light after the excitation source is removed, while fluorescent materials only emit light while the excitation source is present.
Fluorescent materials absorb and emit light almost instantly, while phosphorescent materials absorb and emit light with a delay, continuing to glow after the light source is removed.
Fluorescent material immediately glows when exposed to ultraviolet radiation, that is it fluoresces. Phosphorescent material slowly absorbs and re-emits the radiation it absorbs. This enables phosphorescent material to absorb visible light spectra to "glow in the dark" at a later time.
reflecttion is a part of incidentradiant but emission may be different of incident radiant.

Emission nebula glow and reflection nebula reflect the light form other stars
stimulated emission causes due to the energy difference between the higher and lower energy level state, but it doesn't depends in the case of spontaneous emission . spontaneous emission causes without any stimulation .In stimulated emission energy transfer is twice the energy transfer of spontaneous emission.

The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help
Electronics is a science dealing with electrons emission electrical is a science dealing with electron flow
The California Camry has to meet lower emission standards.
