Fluorescent bulbs contain a gaseous mixture that emits light when electricity passes through it. The waves you see are actually the alternating current (AC) switching on and off at a high frequency (typically 60Hz in the US), causing the light to flicker rapidly, which can create the appearance of waves.

What emits ultraviolet light waves?
Some sources of ultraviolet light waves include the sun, fluorescent light bulbs, tanning beds, and some types of light fixtures and lasers. UV light can also be emitted by certain materials as a result of chemical reactions or other processes.
What best describes the source of electromagnetic waves?
Electromagnetic waves are generated by the acceleration of charged particles, such as electrons, creating oscillating electric and magnetic fields that propagate through space. These waves can be produced by a variety of natural and artificial sources, including the sun, electronic devices, and light bulbs.
What object emits electromagnetic waves?
Objects such as light bulbs, the sun, and electronic devices emit electromagnetic waves. These waves can range from radio waves to gamma rays depending on the source.
Radiant energy is produced by?
Radiant energy is produced by sources such as the sun, light bulbs, fire, and other sources that emit electromagnetic waves in the form of light. It is a type of energy that travels through space in the form of electromagnetic waves.
What are strong light waves?
Strong light waves refer to light waves that have a high intensity or brightness. These waves have a higher amplitude and carry more energy compared to weaker light waves. Strong light waves can be produced by sources such as the sun, lasers, or powerful light bulbs.
Why do fluorescent tubes glow red at both ends only?
It has something to do with the energy waves that are moving through the bulb like a current.
What types of light bulb converts ultraviolet waves in to visible light waves?
A fluorescent light bulb contains a phosphor coating on the inner surface of the bulb, which converts ultraviolet light produced by the mercury vapor inside the bulb into visible light. LED light bulbs do not contain phosphors but instead use semiconductors to directly convert electrical energy into visible light.
What emits ultraviolet light waves?
Some sources of ultraviolet light waves include the sun, fluorescent light bulbs, tanning beds, and some types of light fixtures and lasers. UV light can also be emitted by certain materials as a result of chemical reactions or other processes.
How do you stop uv waves from going through plywood?
uv waves cannot penetrate plywood
What electrical power do light bulbs use?
It doesn't 'USE' any; that is, you don't have to provide any electromagnetic waves in order for a light bulb to do its job.In the course of doing its job, the light bulb PRODUCES light and heat waves.A fluorescent light also produces radio waves.
Can Seismic waves travel through space?
NO! Seismic waves can't travel through space. They are mechanical waves. Mechanical waves require going through mediums and there isn't a medium in space.
Are their risks from CFL bulbs?
Compact fluorescent (CFL) bulbs contain mercury which can present a safety issue if the glass breaks. The broken glass also presents a safety hazard more immediate than mercury. Some CFL bulbs, when operating, generate electromagnetic waves and inject interfering electronic signals into the home power line which can mess up electronic devices and interfere with cordless phones, wifi and radio reception.

What type of light bulb converts ultraviolet waves into visible light?
A fluorescent light bulb converts ultraviolet waves into visible light using a phosphor coating inside the bulb. When the UV light hits the phosphor coating, it emits visible light.
What happens to seismic waves when they pass through the liquid outer core?
There are two types of waves. There are S waves (sheer waves) and P waves (compressional waves). The S waves won't travel through the outer core because it's a liquid, but the P waves will go through it and continue going through the inner core as well.
