When a fluorescent lamp is turned on, the electricity excites the Mercury vapor inside the tube. UV light is produced. The UV light excites the phosphor coating. The phosphorus atoms relax by releasing a visible light. Since the light emitted by the phosphorus atoms is of a spread spectrum (the frequency is not fixed), the light appears whitish. To summarize, electricity is turned into light.

What energy transformations occur in a compact fluorescent light bulb?
In a compact fluorescent light bulb, electrical energy is transformed into light energy through the excitation of mercury vapor atoms inside the bulb. Some electrical energy is also transformed into heat energy due to resistance in the bulb's circuitry and the phosphor coating on the bulb.
Which light bulb uses more energy?
Incandescent and halogen light bulbs use more energy than compact fluorescent lights and LED lights. Fluorescent lamps with magnetic ballasts use more energy than fluorescent lamps with electronic ballasts.
Will a fluorescent light bulb burn brighter than an incandescent one?
Fluorescent light bulbs are typically more energy-efficient and produce more light for the same amount of power compared to incandescent bulbs. So, a fluorescent light bulb may appear brighter than an incandescent bulb with the same power rating.
What are enery transformations of lamp shade?
A lamp shade does not undergo energy transformations itself. It simply diffuses and directs the light emitted by the light bulb within. The energy transformation occurs within the light bulb, where electrical energy is converted to light energy and heat.
What is the energy pathway for fluorescent light?
In a fluorescent light bulb, electricity passes through a gas (such as mercury vapor) causing it to emit ultraviolet light. The ultraviolet light then strikes a phosphor coating on the inside of the bulb, causing it to emit visible light. This conversion process is more energy-efficient compared to incandescent bulbs.
What energy transformations occur in a compact fluorescent light bulb?

What transformations occur in a light bulb?
In a light bulb, electrical energy is transformed into light energy and heat energy.
What type of light is 20w energy saving bulb Halogen Indandecent neon fluorescent etc please help?
The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb.
What is a word that means a light bulb that uses more energy than a fluorescent light bulb?
incandescent
What are the benefits of replacing a fluorescent light bulb with an LED?
Replacing a fluorescent light bulb with an LED can save energy, last longer, produce better quality light, and be more environmentally friendly.
How does a compact fluorescent light bulb work?
A fluorescent light bulb contains a gas which produces UV light when it comes in contact with electricity. Contrary to a normal light bulb this does not create any heat and is far more energy efficient.
What is the swirly light bulb called?
The swirly light bulb is called a compact fluorescent lamp (CFL). It is a type of energy-efficient light bulb that produces light by using electricity to excite the gas inside the bulb to create illumination.
What are the differences between an incandescent bulb and a fluorescent bulb in terms of energy efficiency and lifespan?
An incandescent bulb is less energy efficient than a fluorescent bulb because it produces more heat than light, wasting energy. Fluorescent bulbs are more energy efficient as they produce less heat and more light. Additionally, fluorescent bulbs have a longer lifespan than incandescent bulbs, lasting up to 10 times longer.
The element in a fluorescent light bulb that absorbs UV light and releases visible light energy is?
The element in a fluorescent light bulb that absorbs UV light and releases visible light energy is a phosphor coating on the interior surface of the bulb. When UV light hits the phosphor coating, it emits visible light, creating the illumination we see in fluorescent bulbs.
An electric light bulb is used to light up the room.after a while it also starts to get warm.what is the energy transformations involved?
electrical energy ------> light & heat energy.
Which light bulb uses more energy?
