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.
How do you set up a moth trap?
A sheet with a sticky material on it, is palced in the field with a source of light for example bulbs, tubelights, torch etc. This needs to be done at night. The moths are attracted towards light and they stick to the sheet.
What do light bulbs emit to produce light?
Light bulbs emit electromagnetic radiation, specifically visible light, to produce light.
How tubelights glow in buses?
tubelights in buses are made to glow by the inside being painted with this paint which glows when it comes into conatct with a noble gas for example argon. The paint glows producing a white light
Do light bulbs emit radiation, and if so, what type of radiation do they emit?
Yes, light bulbs emit radiation in the form of visible light.
What types of of energy are the bulbs putting out?
The bulbs are putting out light energy in the form of visible light. If the bulbs are also producing heat, they are releasing thermal energy converted from electrical energy.
Where do visable light waves come from?
Visible light wave sources. Light bulbs and stars are good examples.
What are 3 things that visible light can be emitted by?
stars, flashlights, toasters, CFLs, LEDs, fireflies
What energy is wasted in light bulbs?
Some of the electrical energy is given off as heat not visible light.
What is the difference in fluorescence between incandescent light bulbs and fluorescent light bulbs?
Fluorescent light bulbs produce light by converting ultraviolet radiation into visible light through a process called fluorescence. Incandescent light bulbs, on the other hand, produce light by heating a filament until it glows. The main difference in fluorescence between the two types of bulbs is the method by which they generate light.
Visible light is one example of which energy?
Visible light is a type of electromagnetic waves.
How do Plant light bulbs work?
The fluorescent type of light bulbs (correctly called lamps) have a phosphor that besides emitting visible light (400 to 750 nm) also emits some UV enengy in the UV-A range. Plants need visible light and some UV-A to be effective.
