Why does a fluorescent light bulb glow when rubbed with a piece of nylon or silk in the dark?

Answer 1

Because the electrons from the Nylon cloth or silk are being passed to the light bulb

Answer 2

When a fluorescent light bulb is rubbed with a piece of nylon or silk in the dark, the friction generates static electricity on the surface of the bulb. This static electricity creates an electric field around the bulb, which can ionize the gas inside the bulb. The ionized gas emits photons of light, causing the bulb to glow. This phenomenon is known as triboelectric charging and is a result of the transfer of electrons between the materials.

Answer 3

Well, honey, that's because when you rub nylon or silk on a fluorescent light bulb, you're creating static electricity. This static electricity excites the gases inside the bulb, causing it to glow. So, next time you're bored in the dark, just grab some nylon and put on a light show - just don't set anything on fire!

Answer 4

Oh, dude, that's because when you rub nylon or silk against the fluorescent light bulb, you're actually transferring some of those charged particles onto the bulb. These charged particles excite the gases inside the bulb, causing them to emit light. It's like giving the bulb a little shock to wake it up and make it glow!

Answer 5

Fluorescent bulbs contain a low pressure Mercury vapour. The electricity excites the gas which emits UV light. The inside of the glass is coated with a phosphor. The UV light excites the phosphor which emits visible light.

When you rub the bulb with a piece of nylon you are rubbing electrons from one material to the other (i think from nylon to bulb). This results in static electricity which excites the mercury vapour in much the same way as the electric current in normal operation.

Answer 6

Electrons are transferred from the cloth to the inside of the tube. If there are enough electrons, then they will flow through the tube (creating a current) and the mercury vapor is briefly excited, and the tube will momentarily glow. See related question.

Answer 7

Rubbing a fluorescent light bulb with nylon or silk generates static electricity on the surface of the bulb. This static electricity excites the atoms in the gas inside the bulb, causing them to emit light. The rubbing action transfers electrons between the materials, creating a potential difference that results in the glowing effect.

Because the electrons from the Nylon cloth or silk are being passed to the light bulb
