What was the purpose of the steel coating on a 1943 penny?
The coating is zinc, the core of the coin is steel. Zinc was used to reduce corrosion.
When did tesla invented the fluorescent light?
It was Alexandre-Edmond Becquerel who first conceived the idea of placing a fluorescent coating on the inner surface of a high voltage gas discharge tube but he didn't quite made it work properly. Tesla's investigations in the area of high-voltage RF power processing techniques did result in the very first high efficiency, high frequency lighting ballasts in 1892.
What are the energy transformations of a fluorescent light bulb?
When a fluorescent lamp is turned on, the electricity excites the mercury vapor inside the tube. UV light is produced. The UV light excites the phosphor coating. The phosphorus atoms relax by releasing a visible light. Since the light emitted by the phosphorus atoms is of a spread spectrum (the frequency is not fixed), the light appears whitish. To summarize, electricity is turned into light.
How is fluorescent different from natural light?
Well.. the difference is that fluorescent light isn't natural and natural light isn't fluorescent . its not rocket science (:
What is a fluorescent uranium salt?
A salt which become fluorescent when is irradiated with UV radiations from a UV lamp.
What is the purpose of coating diamond?
Coating a diamond implies that the diamond materials in question are to be put to an industrial use, not a gem-stone use. You can read more about one purpose of coating a diamond, below.
Compact fluorescent lamps have made a lot of changes in the lighting sector it is also changed from a fluorescent lamp to compact fluorescent lamps but still it is dependent on the ballast Why?
A ballast is an electrical component used with a fluorescent bulb (or mercury vapor lamp or arc lamp) to conduct electricity at each end of the tube. Compact fluorescent light bulbs are dependent on ballast because they use a gas to create light. when the gas is excited by electricity, it emits invisible ultraviolet light that hits the white coating inside the fluorescent bulb. The coating changes the ultraviolet light into light you can see.
Lights that glow when an electric current causes ultraviolet waves to strike a coating inside a tube are called?
fluorescent lights
Does a fluorescent bulb specificaly phosphorus reflects ultraviolet radiation.?
There is no phosphorus in a fluorescent lamp, the coating is a compound called phosphor.phosphorus is an element that burns.phosphor is a compound that when excited by an electron beam, UV light, or x-rays glows in visible light.A fluorescent lamp is a mercury vapor UV (aka black light) lamp with a phosphor coating on the inside of the lamp tube to turn the invisible UV light to visible light.
What was the purpose of the steel coating on a 1943 penny?
The coating is zinc, the core of the coin is steel. Zinc was used to reduce corrosion.
What was the purpose of the fluorescent screen in rutherfords experiment?
detect charged particles
How do fluorescent bulbs work?
A fluorescent lamp generates light from collisions in a hot gas ('plasma') of free accelerated electrons with atoms- typically mercury - in which electrons are bumped up to higher energy levels and then fall back while emitting at two UV emission lines (254 nm and 185 nm). The thus created UV radiation is then converted into visible light by UV excitation of a fluorescent coating on the glass envelope of the lamp. The chemical composition of this coating is selected to emit in a desired spectrum.
What is the purpose of mucus on the scales of fish?
The purpose of slime coating is to protect the fish against disease, infection and minor damage.
What are the different gases introduced into fluorescent lamps that give them their specific colors?
I think that you may be confusing fluorescent tubes with neon tubes. Fluorescent tubes use a phosphor coating on the inside of the lamp which is in a limited spectrum. Some tubes are cool white, warm white, and daylight. There is also a gro lux which is on the warm end of the spectrum used for growing indoor plants.
What is the purpose of conformal coating?
Conformal coating is used to cover electrical wiring. It protects the wires from various elements such as dust, moisture, chemicals and extreme heat.
What purpose does enteric coating serve?
An enteric coating that covers medicinal pills is a barrier that controls where in the digestive system that the medicine will absorb. Which enteric coating on pills depends on where the medicine should be absorbed such as the stomach or small intestines.
How does the fluorescent lighting work?
ionized Mercury vapor emits UV light.phosphor coating on inside of tube absorbs UV light and emits visible light.visible leaves tube.
