A light bulb primarily emits light through radiation. When electricity flows through the filament of the bulb, it becomes hot and emits energy in the form of light and heat through radiation. Conduction and convection do not play significant roles in the functioning of a light bulb.
What else can I help you with?
Is a light bulb's heat transfer primarily through conduction, convection, or radiation?
A light bulb's heat transfer is primarily through conduction.
Is a light bulb conduction convetion or radiation?
A light bulb primarily emits light through radiation when electricity passes through the filament, causing it to glow and generate heat. Some heat is also lost through conduction to the base and surroundings, but the main mechanism for producing light is radiation.
Does a light bulb heat the air around it by conduction or radiation?
A light bulb heats the air around it through radiation. As the filament heats up and emits light, it also emits infrared radiation that warms up the air in its vicinity. This is why you can feel the warmth when you are near a lit light bulb.
What is heated by radiation?
Radiation is a method of heat transfer that does not rely on any contact between the heat source and the heated object (as is the case with convection and conduction) Examples of radiation is heat from the sun or from the fliament of a light bulb
What makes a light bulb an example of radiation?
A light bulb is an example of radiation because it emits electromagnetic radiation, in the form of visible light, when an electric current passes through it. This radiation is generated by the excitation of electrons in the bulb's filament, causing them to release photons and produce light.
Is a light bulb's heat transfer primarily through conduction, convection, or radiation?
A light bulb's heat transfer is primarily through conduction.
How can an electric light bulb transfer heat in covection radiation and conduction?
Conduction: Heat travels via Metal parts on Bulb Convection Current: Hot air around bulb rises and cool air replaces it thus heat from bulb will consistantly warm up cool air around it. Radiation: Bulb is bright and shiny, thus emits infra red radiation. These are my opinion and they are not model answers. Mr Lin. from Singapore zillusia100 a.t. yahoo point com point sg

How can conduction be helpful?
Conduction can cause a spark which can light a light bulb. Conduction can be used to heat up metals.

What are you feeling when you feel the warmth from a light bulb on your skin?
Conduction
What is the level of radiation emitted by a light bulb?
The level of radiation emitted by a light bulb is very low and considered safe for everyday use.
Can energy be transferred from one store to another?
Yes, energy can be transferred from one energy store to another through various processes such as conduction, convection, and radiation. For example, electrical energy can be transferred to light energy in a light bulb, or chemical energy can be transformed into kinetic energy in a moving car.
Why does a light bulb give off radiation?
A light bulb gives off radiation in the form of light when the filament inside it heats up to a high temperature, causing it to glow and emit electromagnetic radiation in the visible spectrum. This radiation is what we perceive as light.
Does a light bulb emit infrared radiation?
Yes, a light bulb emits infrared radiation as a byproduct of producing light. Infrared radiation is part of the electromagnetic spectrum and is emitted in the form of heat energy.
