A light bulb radiates visible light when an electric current passes through its filament, causing it to glow and produce light.
A light bulb is designed to take electrical energy and radiate it as electromagnetic energy.It would be nice of all of that energy came out in the form of light, but that has never been accomplished yet. An incandescent light bulb ... the original kind ... radiates much more heatenergy than light energy. In other words, an incandescent light bulb works much more efficientlyas a heater than it does as a source of light.
Here points radiate out from the central idea or concept.
A light bulb that uses a filament is also known as an incandescent light bulb.
The glass covering a light bulb is called a bulb or bulb glass, which protects the filament and controls the direction of light emitted.
No, a light bulb does not have magnets. A light bulb works by passing electricity through a filament, causing it to glow and produce light. Magnets are not used in the operation of a regular light bulb.
By definition, light travels at the speed of light. About 300,000 kps
The current causes heat. The heat is high enough to radiate energy in the form of visible light.
No. Part of the energy is wasted, mainly as heat.
Electricity can be converted to light using light bulb. An incandescence light bulb produce light by passing electricity through filament (resistance) and create heat so hot that it radiate out light. It also can produce light using Electro-luminescence effect as in LED lamb or using ionized gas discharged as in Fluorescent lamb.

Light, whatever the wavelength, does not need a medium in order to radiate.
Thomas Edison is best-known for the light bulb.
