Does a light bulb emit carbons when used?
the electricity used to power the light bulb emit carbon dioxide
Is it true that gas Atoms subjected to electricity emit bright lines of light?
yes, they do emit
What does radioactive materials and electricity have in common?
Electrons. Electricity is composed of free electrons and some radioactive decays emit electrons (beta particles)
Does a physical change emit light?
Yes, for example solar cells produce electricity (physical change) which can then be converted to light energy.
How much carbon dioxide does each light bulb emit?
None. Light bulbs do not emit carbon dioxide. The electricity used to power the light bulb may have been produced by a method which emits carbon dioxide (then again, it may not have), but the bulb itself doesn't emit anything except heat and light.
What process do car headlights use to emit light?
Electric Discharge- the process of emitting light because of electricity passing through a gas.
Hor are LEDs similar to incandescent light bulb?
They emit light and the use electricity. Apart from that, they have little in common, the way they work is completely different.
What do all incandescent materials have in common to cause them to emit light?
They're hot (above about 800 degrees Kelvin).
Do light bulbs emit light or suck dark?
Light bulbs emit light.
What are luminous and non luminous materials?
Luminous means "giving off light", or glows in the dark (since luminosity is detected by the eyes, it usually refers to the visible part of the electromagnetic spectrum). Many materials emit a wide range of radiation other than visible light, which is why some radioactive materials were used as glow in the dark paints, and why the Curies focused on a particular radioactive isotope (because it glowed in the dark). Some materials can even store energy from visible light and emit it later, which is why some of my luminous objects have to be "charged" by a light bulb or the sun. Some chemical combinations can emit light for a while, such as the stuff in lightning bugs, which we can replicate in production lines to make glow sticks. Non luminous materials do not emit light that we can see. Most elements that are not radioactive fall into this category.
Does technetium emit light?
Technetium doesn't emit light.
Do galaxies emit light?
Yes galaxies emit light
