The bulb produces the light.
It depends on the type of bulb.
Incandescent
A light bulb uses electrical energy, and produces light, as well as heat.
A typical incandescent light bulb produces light by heating a filament wire until it glows. The glowing filament produces both visible light and heat.
It produces heat/light
No, they are not the same. A black light bulb produces UVA light.
No, a light bulb is not an electromagnet. A light bulb contains a filament that produces light when current flows through it, whereas an electromagnet is a device that produces a magnetic field when current flows through a coil of wire.
No, it is not recommended to use a regular light bulb in a refrigerator because the heat generated by the bulb can affect the temperature inside the refrigerator and potentially spoil the food. It is best to use a refrigerator-specific light bulb that produces less heat.
Yes, a 100-watt light bulb is brighter than a 60-watt light bulb because it produces more light.
According to the results of science project posted online, beans grew best under a clear light bulb. Beans under a yellow light bulb were second, followed by red and blue.
Thomas Edison is best-known for the light bulb.
