Tube lights are considered a cold source of light because they produce minimal heat compared to other types of lighting such as incandescent bulbs. The majority of energy from a tube light is converted into light, with very little energy wasted as heat. This makes tube lights more energy-efficient and cooler to the touch during operation.

Why tubelight as cold source of light?
Tubelights are considered a cold source of light because they emit light through fluorescence. The fluorescent coating inside the tube absorbs ultraviolet light produced by the energized mercury vapor, causing the coating to fluorescence and emit visible light. This process does not produce excess heat compared to incandescent bulbs, making tubelights a cooler light source.
Which property of light prevents us from seeing a source of light through a bent tube?
Light travels in straight lines, which prevents us from seeing a source of light through a bent tube. When light encounters a bend, it gets reflected or scattered, making it impossible for us to directly see the light source.
What is a energy pathway for fluorescent source?
In a fluorescent light source, electrical energy is converted into light energy through a process called fluorescence. This involves passing an electrical current through a tube filled with a gas and a small amount of mercury vapor. The electrical current excites the mercury atoms, which in turn emit ultraviolet light. This ultraviolet light then causes a phosphor coating on the inside of the tube to fluoresce, producing visible light.
Is tube light translucent?
Yes, a tube light is generally made of a glass or plastic tube that is translucent, allowing light to pass through it. The tube is coated on the inside with phosphor to convert the electrical energy into visible light.
What is the hollow tube of the microscopethrough which light passes?
The hollow tube through which light passes in a microscope is called the body tube or optical tube. It houses the lenses that magnify the specimen and direct light to the eyepiece for viewing.
Is tube light a cold source of light?
yes

How tube light helps people?
Tube light helps by releasing energy coming from its source it helps people to see Try and you will see
What is the source of darkness and cold since the sun is the source of heat and light?
We're modestly familiar with the source of heat and light. And we know that heat and light both exist and are real. Cold and darkness do not exist. They merely describe the lack of heat and light, respectively.
Why laser beam is narrow straightwhere as light from tube light is blury?
A laser beam is a coherent light source that emits a narrow beam of light due to the alignment of its waves. In contrast, light from a tube light is incoherent and emits light in all directions, resulting in a blurry appearance. The difference in coherence and directionality between laser light and tube light accounts for their distinct characteristics.
How does a computer scanner work?
It uses 2 main parts, a light source (usually a cold cathode tube) and a light sensor (similar to that of a photo camera). The two parts are usually on a tray that sweeps the paper at a slow speed so that more detail is captured by the sensor.
How does a tube light works?
tube light woks like a tube light....
