What will happen to the light bulb when you switch off the electric circuit?
There will no longer be current to heat the filament which will then cool and no longer emit visible light. While it is cooling it will continue to emit infrared light for a time.
Does a light bulb emit carbons when used?
the electricity used to power the light bulb emit carbon dioxide
What type of energy does a light bulb emit?
Mainly heat and light. Heat is carried away through convection, but also radiated away as infrared light, a kind of electromagnetic wave (as is light).
What does a white light bulb emit?
light and heat
How does a fireplace emit radiant energy?
In the form of visible and infrared light from the fire.
What is the use of bulb in the circuit?
To emit the generated light?
What is the use of the bulb in the circuit?
To emit the generated light?
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.
Is light emitting diodes emit visible light when forward biased?
It depends on the particular LED. Some of them emit infrared light. But, yes, emission occurs when forward-biased.
What are all bodies emit called?
All objects and living things emit infrared radiation unless the object is not a black hole as well unless its temperature is not at the Absolute Zero ( I would call it an "infrared black hole") - such an object can only absorb infrared radiation.
What are waves given off by a light bulb?
mostly light and heat (infrared)
What happens to the energy wasted in a light bulb?
electircal or photo electrical energy. Photons are shot across from panel to another panel this sparking back and forth creates the light you see.Answer: Electricity is the energy input into a light bulb. It either heats afilamanet to produce heat and light, r excites the gas contained in the bulb (in flluorescent tube) to emit visible light directly or emit UV light which interacts with a phosphor coating in the tubes to emit light.
