What else can I help you with?
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.
How is electricity used to produce light?
Electricity is used to produce light by passing through a filament or gas in a light bulb, which causes the material to heat up and emit light. This process is called incandescence.
What energy is when you turn off a light switch?
Turning off a light switch stops the flow of electricity to the light bulb, which cuts off the energy supply needed for the light bulb to emit light. The energy that was being used to power the light bulb is no longer being converted into light energy.
What element makes light bulb filaments?
Tungsten is the element commonly used to make light bulb filaments. Tungsten has a high melting point, allowing the filament to heat up and emit light efficiently without burning out.
What element is light bulb filaments made of?
Light bulb filaments are typically made of tungsten, due to its high melting point and durability. Tungsten is used for its ability to withstand the high temperatures produced when the filament is heated to emit light.
What is the spectra of fluorescent light?
The spectrum of fluorescent light consists of multiple narrow peaks of visible light, typically in the blue and green regions of the spectrum. Fluorescent lights emit a mix of ultraviolet light that excites phosphors coating the inside of the tube or bulb, which in turn re-emit visible light. The resulting spectrum can vary slightly depending on the specific phosphors used in the bulb.
Which metal is used as filament in bulb?
Tungsten is typically used as the filament in light bulbs due to its high melting point and ability to withstand the high temperatures produced when the filament is heated to emit light.
what is used in a head light or flashlight to create a beam of light?
A light bulb or LED (light emitting diode) is commonly used in headlights and flashlights to produce a beam of light. The light source is powered by a battery or electrical circuit to emit light. Reflectors or lenses are often used to focus and shape the light into a beam.
What type of electromagnetic radiation is used in street lights?
Street lamps are designed to emit visible light. Some of them do this by first emitting ultraviolet radiation that is converted to visible light by a coating on the inside of the light bulb.
Why is krypton used in light bulbs?
Krypton is used in certain types of incandescent light bulbs because it helps prolong the life of the filament inside the bulb by reducing its evaporation. This allows the bulb to emit light for a longer period of time before burning out.
When was the first electric light bulb used?
where was the first light bulb used
How light energy is used in a flashlight?
In a flashlight, light energy is generated by converting electrical energy from the batteries into light through a light bulb or LED. The electrical energy causes the light bulb filament to heat up and emit light, or activates the semiconductor material in an LED to produce light. This light energy is then emitted out of the flashlight to illuminate the surroundings.
