Why heating coil does not emit visible light?
Put enough electrical energy into it and it surely will. As objects heat they emit increasing amounts of Infrared; at a critical temperature atoms will start to produce a first order harmonic - i.e red light. With increasing energy, the statistical population of atoms emitting red light will increase until the object glows bright red. Push in even more energy and you add a second order harmonic one musical fifth above red light - this light is green. Add to the red light and you now have orange. With increasing energy, the statistical population of atoms emitting both red and green light will then increase until the object is bright yellow. Push in yet more energy and a third order harmonic is added; this is one musical octave above red; this light is blue. Eventually, you will be pushing in sufficient energy that the object glows brilliant white. That's how a light bulb does it. However, a heater coil has been designed so that under normal operating conditions it will only produce Infrared
Which state of matter forms when a fluorescent light bulb is turned on?
A fluorescent light bulb produces light by exciting the gas inside it, usually mercury vapor or neon. The excited gas atoms emit ultraviolet light, which stimulates a phosphor coating on the inside of the bulb to produce visible light. So, when a fluorescent light bulb is turned on, it emits light through a process involving excited gas and phosphor.
What is the speed of light in gold?
The speed of light in a material like gold is slower than in a vacuum, as light waves interact with the atoms of the material. In gold, the speed of light is approximately 0.63 times the speed of light in a vacuum.
Why not all metals emit colors in the flame test?
Not all metals emit colors in the flame test because the color emission is determined by the specific arrangement of energy levels in their electrons. Only metals with electrons that can be easily excited to higher energy levels and then return to their ground state by emitting light will produce a visible color in the flame test. Metals with a more complex energy level structure may not emit visible light during the test.
Does a prism separate light into only the visible spectrum or the entire spectrum?
A prism separates light into the visible spectrum, which includes the colors of the rainbow. It does not separate light into the entire electromagnetic spectrum, which ranges from gamma rays to radio waves.
Do atoms in an incandescent gas absorb or emit light?
When they exit their exited state. When an atom is bombarded by photons, it will often times absorb the photon. A photon is a unit of energy, so this energy is added to the atom, "extiting" it. However, atoms may only remain in ths excited state for a short period of time, and will eventually release the photon, reemiting it as light, and then the atom will return to its normal state.
Does not emit light?
The sun is the only object in the solar system that generates and emits visible light. Any of the others is a correct answer to this question.
What color light is emitted by radio waves?
Radio waves do not emit visible light. Only light with wavelengths of roughly 4*10^-7 to 7*10^-7 meters are visible.
What color would a ununoctium light glow?
Ununoctium, element 118 on the periodic table, is a synthetic element and its properties are not well-studied. It is unlikely to emit visible light on its own because of its high radioactivity and short half-life. If it were to emit light, it would likely glow a bluish color due to its atomic properties.
Is heat visible?
No, heat is not visible to the human eye. We can only see objects that emit or reflect light, but heat itself is a form of energy that is detected by our skin or other instruments.
What objects in space emit or reflect light?
Stars, planets, moons, comets, and asteroids emit or reflect light in space. Stars produce their own light through nuclear fusion, while planets and moons reflect light from the Sun. Comets and asteroids can also reflect sunlight, making them visible in the night sky.
Does the sun and moon emit light?
the sun only emit light. not the moon. it will reflect the light of the sun.
Does Venus emit or reflect light?
All planets only reflect light. Only stars, like our sun, emit.
Which is considered a special property that applies to only a few minerals?
Fluorescence is a special property that only applies to a few minerals. It refers to the ability of a mineral to emit visible light when exposed to ultraviolet light.
Does every light source emit only one type of light, or can some light sources emit multiple types of light?
Some light sources can emit multiple types of light, such as white light sources that emit a combination of different colors.
Name some stars that don't emit light?
Black holes and neutron stars are examples of stars that do not emit visible light. They can only be detected by their gravitational effects on nearby objects or through other forms of radiation such as X-rays or radio waves.
Why ordinary silicon diodes do not emit light?
Silicon is opaque to all light (IR through UV).The bandgap of silicon is not high enough to produce visible photons, only IR photons.
