Phosphorescence is similar to what other source of light?
Phosphorescence is similar to fluorescence in that both involve emission of light by materials after they have absorbed energy. The main difference is the time scale: fluorescence is immediate, while phosphorescence has a delay before light is emitted.
Why was Benri Becquerel interested in phosphorescence?
Becquerel was interested in phosphorescence because it involves materials that emit light after being exposed to a source of energy, such as sunlight or electricity. He wanted to better understand this phenomenon and its underlying mechanisms, which ultimately led to his discovery of radioactivity.
What is the energy pathway for a phosphorescent light source?
Phosphorescent light sources convert electrical energy into light energy through a process called phosphorescence. When the phosphor material in the light source absorbs energy from an external source, such as electricity, it temporarily stores this energy and then releases it as light over an extended period of time. This delayed emission of light is what gives phosphorescent materials their characteristic glow after the initial energy source is removed.
What is the Major source of light?
hot objects, i.e. incandescencereemission of absorbed light, i.e. fluorescence (immediate), phosphorescence (delayed)relaxation of excited electrons to lower energy levels in atoms, e.g. LEDs, neon lightstriboluminescenceetc.
What substances absorb energy from an outside source and then emit some of it as visable light even after the source is removed?
Phosphorescent materials are substances that can absorb energy from an outside source (such as light or heat) and then emit some of that energy as visible light even after the source is removed. This delayed emission of light distinguishes phosphorescence from fluorescence, which emits light instantaneously upon excitation. Examples of phosphorescent materials include certain types of glow-in-the-dark products and paint.

The ability of a mineral to continue to glow for a period of time once an ultraviolet light source is removed is known as?
phosphorescence
What is phosphorescence?
Phosphorescence is a type of light emission that continues for some time after the excitation source is removed. It occurs when certain materials absorb energy and then release it slowly as light. This phenomenon is often seen in glow-in-the-dark items.
What is the definition of the word phosphoresent?
Phosphorescent refers to the quality of glowing in the dark after exposure to light. It is a type of luminescence that persists for some time even after the light source has been removed.
How does phosphorescent effect diamond?
When a diamond is exposed to ultraviolet light, some diamonds containing impurities or structural defects can exhibit phosphorescence. This is due to the trapping of excited electrons in the crystal structure that are slowly released as visible light after the UV source is removed. The specific color and duration of phosphorescence can vary depending on the impurities or defects present in the diamond.
An object that gives off its own light is said to be?
such objects are identified with the suffix -escence where the root word is the element that is responsible for the light. When you have Florine as the source of the light you have fluorescence. When you have phosphorus as the source of the light you have phosphorescence. and so on. theoretically every element could contribute to this.

What can glow in dark without a energy source?
There is no energy transformation without energy source. It is that the energy source is not battery. Glow-sticks utilize a chemical energy to generate light so it had internal energy source. Phosphorescence or Glow in the dark stored light energy in the form of electron state and re-emitted the light later. Energy is stored in the molecule and thus its' molecule is the energy source.
