What is the difference between a phosphorescent source and a fluorescent source?
phosphorescent is glowing in the dark;reusing old light it has stored, like a glow in the dark keychain fluorescent is something that glows when energy is applied to it, such as the fluorescent lightbulb Answer As the name implies, phosphorescent comes from the element phosphorus. Many other substances which are not phosphorus can fluoresce at certain wavelengths of light. I agree phosphorous like sea waves sometomes.

The main difference between the two is the lasting power of the glowing. Phosphorescent materials glow for a longer period of time, and what's usually considered 'glow in …the dark'. Fluorescent glows under blacklight, but this light does not remain at all afterwards.
Classically, phosphorescent substances absorb energy and then re-emit it for an extended time afterwards. Fluorescent substances "down-convert" higher frequencies to low…er frequencies and don't emit after the energy source has been removed. Boosting the energy levels of orbiting electrons that fall back to lower levels and thus emit a photon, produce light. There are also other ways to do this--incandescence (by heat), bioluminescence (little creatures' chemistry), triboluminescence (friction), chemiluminescence (chemistry), electroluminescence (electrically), sonoluminescence (by sound waves), Bremstrahling (atomic braking radiation) and more.
Fluorescence is light energy produced by a process where high-energy radiation (such as ultraviolet or X-ray) is absorbed by electrons surrounding an atom and is re-emitte…d as light energy. Phosphoresence is light energy produced by a particular type of chemical reaction where the excess chemical energy of the reactants is given off as light energy.
Fluoresent light bulbs are run using electricity.. phosphorescentlight are not,, they have particles inside that absorb from light sources of any kind and store it awa…y to be used , that's why they are not glowing all the time.
The basic idea of a source is as follows: A source produces something (a spring is a source). A sink consumes something (a hole in the ground that water pours into is a si…nk hole). But in biology, the terms have more specific meaning. That "something" is referring to carbohydrates. "The movement of carbohydates occurs from where carbohydates are made or have been stored, called a source, to where they will be stored or used, called a sink."
Sources may be someone's personal viewpoint of what happened, and may be made up by the person. Evidence expresses facts about the past - meaning what really happened; the tr…uth; the reality of an event, situation or person.
Fluorescent material immediately glows when exposed to ultraviolet radiation, that is it fluoresces. Phosphorescent material slowly absorbs and re-emits the radiation it a…bsorbs. This enables phosphorescent material to absorb visible light spectra to "glow in the dark" at a later time.
A source is some type of original material such as diaries or artifacts that gives you information. Evidence is information that is relevant in proving a disputed fact for… a legal proceeding.

Bioluminecence , or a symbiotic arraignment between an animal and a bacteria, is a natural light source given off by a living organism.
Source is a place where one can obtain any valuable thing, for example 1. Well/Waterfall is a source where one can obtain water. 2. The Sun is the source for light to live… animal and trees. 3. School is a source to obtain knowledge. Resource is anything which is valuable that one consume to perform a function, for example 1. Teacher is a resource when a student learns 2. Petroleum is a resource in may aspect 3. Computer RAM,Processor and Disks are resources when a program runs K.M. Anura Wijayasingha
A source is one item usually a book or evidence or a person like a witness. A resource is something or a pile of something that you use and come back to repeatedly like stone …or gold or wood. Sources or usually referring to information like news reports or professor's books or scientific facts or the like. resources are things you can reuse or repeatedly use in a way you would use like a water pump for water or a forest for trees and logs.
