What else can I help you with?
What protects the skin from ultraviolet radiation?
Melanin is a substance produced by the skin that protects the skin from ultraviolet radiation. It also gives skin its color.
What are the positive points of ulteraviolet rays?
Ultraviolet rays can be used as for fluorescent lamps as certain chemicals glow when they absorb ultraviolet. In fluorescent lamps, the sindide of the tube is coated with a white powder that gives off light when it absorbs ultraviolet. The ultraviolet is produced by passing a current through a gas in the tube.
What Is the gas that is produced by the ultraviolet radiation in the air in the vicinity of welding operations?
Ozone is the gas produced by ultraviolet radiation in the air near welding operations. Ultraviolet radiation can break down oxygen molecules in the air into oxygen atoms, which can then combine to form ozone. Ozone can be harmful to human health and the environment.
Is the light produced by fluorescent lights potential kinetic or radiant energy?
The light produced by fluorescent lights is radiant energy. It is in the form of electromagnetic radiation that is visible to the human eye.
What kind of energy does a fluorescent light produce?
Main one is light energy. Also some heat is produced
Is fluorescent light produced by heat?
Fluorescent light is not produced by heat. It is produced when electricity passes through the mercury vapor in the fluorescent tube, causing the mercury atoms to emit ultraviolet light that then interacts with the phosphor coating inside the tube to produce visible light.
What color does argon produce in a fluorescent tube?
Argon gas by itself does not produce a specific color in a fluorescent tube. It is typically used as an inert gas filler in fluorescent tubes to prevent degradation of the electrodes and enhance the performance of the tube. The color produced in a fluorescent tube is usually due to the phosphor coating on the interior of the tube, which emits visible light when excited by ultraviolet radiation emitted from the tube's gas discharge.
What makes things fluorescent?
Fluorescence is produced when an electron excited by an e.m. radiation returns to the ground state and emit a photon.
What are fluorescent light bulbs inner wall coated with?
Fluorescent light bulbs have an inner wall coated with phosphor powder. This coating converts the ultraviolet light produced by the bulb into visible light when it strikes the phosphor.
What is atmospheric ozone produced from?
Atmospheric ozone is mainly produced from the reaction of oxygen molecules (O2) with ultraviolet (UV) radiation from the sun. This reaction results in the formation of ozone molecules (O3) in the stratosphere. Ozone can also be produced from human activities, such as the release of certain pollutants and chemicals.
What is sun burns?
Sun burn is a burn to living tissue such as skin produced by overexposure to ultraviolet, radiation, commonly from the sun's rays.
What is a Form of non-nuclear radiation?
One form of non-nuclear radiation is electromagnetic radiation, which includes visible light, infrared radiation, ultraviolet light, microwaves, and radio waves. These forms of radiation are produced by the movement of charged particles and do not involve any nuclear reactions.
