Quesiton : Which type of electromagnetic wave causes a chemical to glow in a fluorescent light bulb?

Answer: ultraviolet waves

Which type of electromagnetic wave causes a chemical to glow in a fluorescent light bulb? Ultraviolet light is a type of electromagnetic radiation as are radio waves infrared radiation X-rays and gamma-rays. UV light which comes from the sun is invisible to the human eye. It makes black-light posters glow and is responsible for summer tans — and sunburns. How can the answer be improved? Ask students if they think that different types of light will affect how well a phosphorescent object will glow. 2. Show students four different light sources: an incandescent light bulb a fluorescent light bulb an infrared light bulb and an ultraviolet light bulb. 301 Moved Permanently. nginx This type of electromagnetic radiation (i.e. light) production is a quantum phenomenon in which the absorption of energy (such as from ultraviolet radiation) "excites" the outermost electrons surrounding the nuclei of the atoms of the absorption material. A light bulb radiates energy in form of electromagnetic waves . Most of them are in the infrared part of the spectrum (heat) some visible light and some in higher regions of t … he spectrum (ultraviolet) especially bulbs with very high filament temperature (halogen). Mon Dec 05 2011 00:00:00 GMT+0530 (IST) · a bulb is placed on a wire parallel to the direction of the electric field. The bulb is directly on the x-axis where the two waves cross each other. 1. Would the bulb glow when the wire is parallel to the direction of the electric field? The wire containing the bulb is now shifted up a distance on the plane of the electric field 2. In matter if the matter allows an electromagnetic wave to propagate the speed is slower than the speed of light and in optics we say the speed is reduce by the index of refraction v=c/n. Ultraviolet light is a type of electromagnetic radiation that makes black- light posters glow and is responsible for summer tans — and sunburns. This video on Facebook shows someone using an " electromagnetic radiation detector" to show that the new energy-efficient light bulbs give off alarmingly dangerous amounts of radiation. In physics electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta photons) of the electromagnetic field propagating (radiating) through space carrying electromagnetic radiant energy. It includes radio waves microwaves infrared (visible) light ultraviolet X-rays and gamma rays. Ultraviolet light is electromagnetic radiation just like visible light but it is slightly more energetic. Undetectable by the human eye when UV light hits certain materials called phosphors it causes them to glow .
