What else can I help you with?
Could an ordinary glass can serve as the glass bulb of a bulb?
Sure. But before you can use it to provide light, you need to find a way to take all the air out of it, and seal it so that no air gets back in. If air gets into a light bulb, the bulb immediately burns out.
How do you make a light bulb in little alchemy?
Light and glass. Light: electricity (Energy + Metal) Energy: Fire + Air Metal: Fire + Stone Stone: Air + Lava Lava: Earth + Fire Glass: Fire + Sand Sand: Stone + Air Your welcome :)
Why does the original light bulb have a point on the top?
The point on the top of an original light bulb was used as a seal to prevent air from entering the bulb and causing the filament to burn out quickly. It helped maintain a vacuum inside the bulb, which is essential for the light bulb to function properly.
Why is there hardly any air in a glass bulb?
Hi! This is the question for this question! Because air was contained with oxygen and oxygen so oxygen with smallest heat it burns down the filament! This is also evacuated and filled with a gas which does not react with the red hot filament. So .... if air present the filament would quickly oxidise and fail to light up!
What does a light bulb have to do with an electrical light source?
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
How was a light bulb made?
A light bulb is made by creating a glass bulb, evacuating it of air, adding a tungsten filament, sealing the bulb, and then connecting it to a power source to produce light when heated. The process is carefully controlled to ensure the right conditions for generating light efficiently and safely.
Why does an electric bulb bang when it is broken?
Light bulbs have most of the air removed, that is there is a partial vacuum inside the bulb. So, when they break atmospheric pressure pushes the on the glass where it is weakened and air rushes somewhat violently into the bulb.
Why is the filament of a light bulb surrounded by glass?
The glass surrounding the filament in a light bulb serves as a protective barrier. It helps to prevent the filament from oxidizing (burning up) when exposed to oxygen in the air, which could cause the filament to fail prematurely. The glass also helps to contain the heat generated by the filament and allows light to pass through while providing structural support for the bulb.
Why is there so little air in the glass bulb?
The air in the glass bulb is limited to create a vacuum seal, which helps protect the filament from oxidation and burning out when the bulb is lit. The vacuum also prevents the formation of hot air pockets that can shatter the glass due to thermal expansion.
When light enters glass from air it changes direction. What is the change of direction called?
If the light is entering from air or a vacuum, the light will slow down. The affect of this, if the light hits the glass at an angle, is that the direction of the light will change.
Why is argon used instead on air in the light bulb?
The filament in the light bulb is heated to a very high temperature. At such a temperature oxygen from the air would oxidise the metal(s) in the filament and thereby destroy the bulb. Using an inert gas such as argon in the bulb prevents such oxidation.
What is the hot filament protected by?
The hot filament in an incandescent light bulb is protected by a glass bulb filled with an inert gas, such as argon or nitrogen. This gas prevents the filament from reacting with oxygen in the air, allowing it to glow and produce light.
