What else can I help you with?
Why are there no substances that convert visible light into UV?
UV has higher energy (per photon) than visible light.
Does UV have a longer wavelength or visible light?
Infrared has a smaller wavelength than microwaves.
If you compared the frequencies of UV light an visible light you and rsquod find that the UV light had a smaller frequency.?
UV has a HIGHER frequency than visible light. If you get such results, either you are not measuring the correct light, or something else is wrong with the measurement.
Why do UV tubes glow blue even though UV radiation is invisible to the human eye?
UV tubes contain a phosphor coating that absorbs UV radiation and re-emits it as visible light, giving off a blue glow. This visible light is what we see, even though the UV radiation itself is not visible to the human eye.
Does a fluorescent bulb specificaly phosphorus reflects ultraviolet radiation.?
There is no phosphorus in a fluorescent lamp, the coating is a compound called phosphor.phosphorus is an element that burns.phosphor is a compound that when excited by an electron beam, UV light, or x-rays glows in visible light.A fluorescent lamp is a mercury vapor UV (aka black light) lamp with a phosphor coating on the inside of the lamp tube to turn the invisible UV light to visible light.
Why are there no substances that convert visible light into UV?
UV has higher energy (per photon) than visible light.
How do plants convert UV rays into food?
they don't convert UV into food, but they can convert visible light into food through photosynthesis. UV can be damaging to the plant and is one of the reasons they have a waxy cuticle covering the leaves
What produces uv light?
UV light is produced by various sources including the sun, black lights, tanning beds, and UV lamps. Specialized materials can also convert visible light into UV light, such as fluorescent materials in fluorescent bulbs.
Visible light fits between x-rays and uv?
No, the visible light region is between Infra-red and UV.
What color are UV rays?
Colour only applies to visible light. UV rays are not visible.
How can you see the UV light in laminar air flow otherwise usually you cant see the uv ray?
UV light in laminar airflow can be seen by introducing a UV light-reactive substance, such as fluorescein or UV powder, into the air. When UV light interacts with these substances, they emit visible light, allowing you to visualize the airflow patterns. This technique is commonly used for testing and validating the effectiveness of laminar air flow systems.
Does UV have a longer wavelength or visible light?
Infrared has a smaller wavelength than microwaves.
If you compared the frequencies of UV light an visible light you and rsquod find that the UV light had a smaller frequency.?
UV has a HIGHER frequency than visible light. If you get such results, either you are not measuring the correct light, or something else is wrong with the measurement.
How do you make a distinguish between UV and VIS?
The only difference, between ultra violate light and visible light, is their frequencies, UV has higher frequency than visible and since wavelength x frequency = the speed of light (which is constant at 3x108 ms-1), therefore wavelength is higher in UV. UV light is also not visible, unlike visible light! so, in summery the difference is frequency and wave length.
Why do some materials glow in ultraviolet - UV - light?
UV light is invisible to the human eye, which is why it is sometimes referred to as 'black light'. However, some materials (e.g. DayGlo) can absorb UV energy and convert it into visible light energy. They are said to be fluorescent.
Which form of visible light is harmful?
UV (ultra violet) light
Descrbe What happen at the atomic level when a substance fluoresces under UV light?
uv light causes.... excitation of electrons of atoms.... leading two phenomenon absorption frequency emmision frequency... read about the principles involoved u will get to know urself.....!!
