Why is there no substance that convert visible light to UV?
UV photons have more energy (less wavelength, higher frequency) than visible light photons. It is possible to convert photons to ones with less enery, but not the opposite.
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.
What are the limits of the period of visible light?
Just beyond the limits of visible light are ultraviolet (UV) and infrared (IR) light.
Does UV have a longer wavelength or visible light?
Infrared has a smaller wavelength than microwaves.
Does a prism separate light into only the visible spectrum or the entire spectrum?
Well, seeing as it seperates visible light, it follows that it only seperates that visible light into the visible spectrum. You can't make radiowaves or UV rays out of 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
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.
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 long is semen visible on skin in UV or black light after you wash?
Yes, you can use a black light on bed sheets or where-ever and the semen will be visible.
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.
Which form of visible light is harmful?
UV (ultra violet) light
What are the limits of the period of visible light?
Just beyond the limits of visible light are ultraviolet (UV) and infrared (IR) light.
Does UV have a longer wavelength or visible light?
Infrared has a smaller wavelength than microwaves.
Visible light x-ray and uv have the same what?
speed
