The UV region typically refers to electromagnetic radiation with wavelengths between 10 nm and 400 nm, encompassing the ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC) regions. This range is just beyond the violet end of the visible spectrum. UV radiation is commonly categorized as UVA (315-400 nm), UVB (280-315 nm), and UVC (100-280 nm) based on the wavelengths involved.

Why you are use monochromator in uv spectroscopy?
A monochromator in UV spectroscopy is used to isolate a specific wavelength (or range of wavelengths) of light from the UV region of the spectrum. This helps in achieving better wavelength selectivity and accuracy in UV spectroscopic measurements by allowing only the desired wavelengths to pass through to the sample.
What is red solution in uv spectroscopy?
In UV spectroscopy, a red solution could indicate the presence of a compound that absorbs light more in the visible range rather than in the UV range. This could be due to the presence of colored impurities in the sample or the compound itself having strong absorbance in the visible region. Further analysis, such as UV-Vis spectroscopy, can provide more information on the specific properties of the red solution.
Which has the lowest frequency uv- b uv- a uv- c?
UV-C has the lowest frequency among UV wavelengths. UV-C rays range from 100 to 280 nm, while UV-A and UV-B have longer wavelengths and higher frequencies. UV-A ranges from 315 to 400 nm, and UV-B ranges from 280 to 315 nm.
Where does the UV ray get absorbed?
UV rays are mainly absorbed by the ozone layer in the Earth's stratosphere. The ozone layer acts as a protective barrier, absorbing most of the UV radiation before it reaches the Earth's surface. Some UV rays still penetrate the atmosphere and reach the Earth's surface, where they can be absorbed by air, water, and land.
How do hetero cyclic compounds absorb UV light?
Heterocyclic compounds absorb UV light due to the presence of conjugated pi electron systems within their ring structures, which allows for the absorption of light energy. The electrons in the pi system can be excited to higher energy levels by the UV light, resulting in absorption and subsequent electronic transitions.

Is Dimethylformamide DMF suitable for UV spectroscopy detection?
Yes, Dimethylformamide (DMF) is suitable for UV spectroscopy detection as it has a wide UV absorption range that allows for analysis in this spectral region. However, it is important to consider that DMF itself absorbs UV light, so baseline correction and appropriate blank subtraction are necessary for accurate measurements.
What is the frequency range of UV?
540-950 THz
Why during the month of September is the UV range so large?
The UV range is large during September due to spring season. It is the time when the ozone depletion is maximum.
Which atmospheric gas is primarily responsible for filtering sunlight in the 120-220nm region?
Ozone is primarily responsible for filtering sunlight in the 120-220nm region of the atmosphere. This region is known as the "ozone absorption range" because ozone molecules absorb most of the incoming solar ultraviolet radiation in this range, which helps protect living organisms on Earth from harmful UV rays.
Which has the lowest frequency uv- b uv- a uv- c?
UV-C has the lowest frequency among UV wavelengths. UV-C rays range from 100 to 280 nm, while UV-A and UV-B have longer wavelengths and higher frequencies. UV-A ranges from 315 to 400 nm, and UV-B ranges from 280 to 315 nm.
Visible light fits between x-rays and uv?
No, the visible light region is between Infra-red and UV.
Frequency and wavelength of uv light?
UV light has a frequency range of approximately 7.5 x 10^14 Hz to 3 x 10^16 Hz. The corresponding wavelength range is about 10 nm to 400 nm, depending on the specific type of UV light (UV-A, UV-B, or UV-C). UV light is invisible to the human eye but has important applications in various fields such as sterilization, fluorescence, and phototherapy.
Does communication satellites transmit UV rays?
No. No point, radio waves have much better range than UV rays.
Will the absorption at 375nm have any effect on the colour of the anthocyanin?
There will be no effect. 375nm is in the UV region and lies outside the visible region.
