(long story short) Because just like you, you grow older than eventually die :)
Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers.
Fluorescent bulbs generate light by using an ionized gas and electrical discharge, whereas regular light bulbs generate light by using heat within the filament contained in the bulb.
Heat.
Well i use T.V bulbs Computer and i always sun bbaith in the sun i have a Nintendo Ds what gives away light a glow worm a electric bar fire and i also have a fire what gives away light lightening and expecially the stars.
no
because it doesn't let the light glow
Fluorescent bulbs contain mercury vapor that emits ultraviolet light when electricity excites it. The ultraviolet light then hits a phosphor coating inside the bulb, causing it to glow and produce visible light.
It might be the energy saving bulbs.
To make light bulbs glow dimmer, I reduced the amount of electricity flowing to them by using a dimmer switch or a lower wattage bulb. This decrease in electricity causes the filament in the bulb to emit less light, resulting in a dimmer glow.
Incandescent light bulbs do not emit much Ultraviolet light. Strip lights and compact fluorescent low energy light bulbs do. The whiteners added to white fabrics react to UV light and glow due to fluorescence.
To make light bulbs glow brighter, you can increase the voltage supply to the bulb. This will cause more current to flow through the filament, resulting in a brighter glow. Be cautious not to exceed the recommended voltage rating of the bulb, as this can lead to overheating and damage.
The sun, light bulbs, fire, stars, and glow sticks emit light.
The phosphors in fluorescent bulbs absorb ultraviolet light, which is emitted by the bulb's mercury vapor when electricity is passed through it. The absorbed ultraviolet light is then re-emitted as visible light, creating the glow we see.
Sun, moon, stars, light bulbs, candles, fireflies, and glow sticks.
Light bulbs are designed to produce light when electricity passes through the filament, causing it to heat up and emit photons. As long as there is a continuous flow of electricity, the filament will continue to glow and the light bulb will remain lit.
Mercury vapor gas in fluorescent light bulbs helps to produce ultraviolet light when an electric current passes through it. The ultraviolet light then causes the phosphor coating inside the bulb to glow and produce visible light.
The wiring inside the light bulb is very thin (the filament) and glows when heated. The current through the thin wire heats up the filament wire so that it will glow. See the related link 'How Light Bulbs Work'.
