What element is used in fluorscent light with Argon?

Mercury is the element used in fluorescent lights with argon. When electricity is passed through the mercury vapor inside the light tube, it produces ultraviolet light that excites the phosphor coating on the inside of the tube, creating visible light.


Are mercuric oxide and argon gas in tube light?

Argon gas is commonly used in fluorescent tube lights as a filler gas, while mercuric oxide is not typically used in tube lights. Instead, mercury vapor is used in conjunction with argon gas to produce ultraviolet light that activates the phosphor coating inside the tube to produce visible light.


Which gas is found in tube light?

Tube lights contain a small amount of mercury vapor gas, which is used to produce ultraviolet light when an electric current passes through it. This ultraviolet light then causes the phosphor coating inside the tube to fluoresce and emit visible light.


How discharge tube is different from tube light?

A discharge tube is a type of gas-filled tube that emits light when an electric current passes through it, commonly used in neon signs or plasma displays. On the other hand, a tube light is a type of fluorescent lamp that uses a phosphor coating inside a glass tube to produce light. While both types of tubes rely on gas and electric current to produce light, they differ in their construction and application.


How is total internal reflection used in an endoscope?

the light that is sent down the tube reflect of the sides making the light 'bend' down the tube and making it use internal reflection. once it gets to the end of the tube inside the patient, the image is reflected back to the person on the outside so they can see inside.


What is photoconductive cameratube?

A photoconductive camera tube is a type of electron tube used in early television cameras. It works by converting light into electrical signals. When light falls on the photoconductive materials inside the tube, they change their electrical resistance, allowing the tube to capture and convert the light information into an electronic signal.


What gas is used inside a light bulb?

Argon gas is commonly used inside incandescent light bulbs to prevent the filament from oxidizing and burning out. It helps to prolong the life of the bulb by reducing the evaporation of the filament material.


Why tube light glowing white colour?

Mercury is present inside the tube light.When we give supply to the tube light the mercury vapours excites and it produces uv radiation which then strikes the fluorescent material and produces light. Therefore it is called fluorescent light.


Why light emitted by a bulb is yellowish in colour but from a fluroscent tube is white?

The color of light emitted by a bulb is determined by the material of the filament which usually emits a warm, yellowish light. Fluorescent tubes produce white light by using a phosphor coating on the tube that converts UV light into visible light of different colors, resulting in a more natural white light.


What is the function of capillary tube?

The capillary tube is used on the inside of the refrigerators. It is a long copper tubing that is used as a thruster.


Why do optical fibers carry light long distances?

Imagine a plastic tube with an inside surface that is a high quality mirror. If you were to direct light into one end of this tube the light would bounce of the mirrored walls of this tube indefinitely, (regardless if the tube curves or twists) and you will see the light at the other end. if you were to send the light in an organised code it can then be used in communication. In scenes this is how fibber optics works. fibre optics are made with super fine quality glass drawn out to about the thickness of a human hair with plastic coatings around them to make the inside of the grass reflective and protect it.
