UV has a wavelenght of 400nm and less
you can calculate the frequency with this formula
V (frequency) = c (speed of light) / λ (wavelenght)

Which is the most harmful UVB or UVC?
UV-B and UV-C are filtered by the ozone layer present in the atmosphere and only UV-A reaches to the earth which cause the various skin infection. if we talk about the frequency of the UV-B and UV-C the because of the higher frequency the UV-C is more harmful. UV with the wavelength of 253.7 nm is used for its germicidal activity.
Does UV or red light have more energy?
UV light has higher frequency, so it has more energy than red light has
What has a lower frequency and longer wavelength Orange light or violet light?
orange
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.....!!
What is the kinetic energy of the emitted electrons when cesium is exposed to UV rays of frequency?
3.72*10^-19 j
Which has the lowest frequency uv- b uv- a uv- c?
UV-A
How are uv rays are harmful?
UV rays are very harmful. It is because of the high frequency that they carry.

What is the frequency range of UV?
540-950 THz
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.
Is UV light emitted from all lasers?
No, most lasers emit light at a different frequency than UV.
Can you change the frequency and wavelength of UV rays?
No dont try it
Are uv and infra red light visible?
"UV" (ultra-violet) is radiation with shorter wavelength/higher frequency than visible. Infrared is radiation with longer wavelength/lower frequency than visible.
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.
How uv rays affected biological system?
UV rays are high frequency rays. They affect the biological system by killing beings.
Does UV or red light have more energy?
UV light has higher frequency, so it has more energy than red light has
What does ultraviolent radiation originate from?
UV originate from sun. these are high frequency rays.
