Short UV refers to ultraviolet light with wavelengths between 100-280 nm, while long UV refers to wavelengths between 280-400 nm. Short UV is more harmful to human skin and eyes, causing sunburn and potential long-term damage, while long UV is less harmful but still has the potential to cause skin aging and eye damage.

What is the difference between UV light and IR light?
UV light has shorter wavelengths and higher energy than IR light. UV light is typically used for sterilization and disinfection, while IR light is used for communication, remote controls, and heating applications. UV light is also more harmful to living organisms, including humans, compared to IR light.
What is the wave length of UV?
The wave of UV is shorter then visible light but longer then x-ray waves. It ranges between 400nm and 10nm.
What is the difference between UV lamps and IR lamps?
UV lamps emit ultraviolet light, which is invisible to the human eye and is commonly used for disinfection purposes. IR lamps emit infrared light, which is also invisible but is used for applications such as heating or drying. The main difference is the wavelength of light they emit and their respective uses.
What is the difference between UV protected lenses and polarized?
UV lens coatings are designed to block UV rays from reaching your eyes. Polarized lenses block glare (light reflected off of water or snow, for example) and improve vision that way. Polarized lenses do not offer UV protection - they would need to have a UV coating applied.
What type of waves do black light use?
Black light uses ultraviolet (UV) waves, specifically UVA waves with longer wavelengths compared to other types of UV light. These waves are shorter than visible light waves and can cause certain materials to fluoresce or glow when exposed to them.
What are the short and long term effects of UV?
Haha
What is the difference between a UV stabilizer and a UV absorber?
A UV stabilizer helps extend the lifespan of a material by preventing UV-induced degradation, while a UV absorber absorbs UV radiation and converts it into harmless heat, reducing the material's exposure to UV rays. Stabilizers work over the long term to maintain material integrity, while absorbers provide short-term protection by dissipating UV energy.
Difference between UV valve and XV valve?
XV is shutoff valve UV is under control valve
What is different between pda detecto and uv detector?
technical difference is flow cell is placed in between lamp and optics but in uv it is placed after grating. and flow cell receives monochromatic light in uv detector but polychromatic in pda.
What is the difference between eureka aquasure aquaflow dx and aquasure storage uv purifier?
AquaSure Aquaflow Dx is a multi stage UV water purifier whereas AquaSure Storage UV is a 4 stage UV electric water purifier.
What is Difference Between HPLC UV detector Spectrophotometer uv detector?
HPLC UV detector is a component used in high-performance liquid chromatography (HPLC) to monitor eluent absorbance, while a spectrophotometer UV detector is a standalone instrument used to measure the absorption of light at different wavelengths. HPLC UV detectors are specifically tailored for chromatography applications, whereas spectrophotometer UV detectors are more versatile and used for various analytical purposes.
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.
What are harmful effects of UV rays?
Sun burns are short-term effects. Cancer of the skin could be long-term effects.
How does hair help a mammal maintain its body temperature?
In colder climates, mammals have long hair, which keeps them warm. In warmer climates, mammals have short hair, which serves as a barrier between the UV rays from the sun and the mammal's skin.
What are the UV active inactive compound?
UV active compounds are substances that absorb UV radiation and exhibit a response, such as fluorescence. UV inactive compounds do not absorb UV radiation or show any response under UV light. These distinctions are important in various applications, such as sunscreen formulation or forensics.
Are Black Lights Safe?
Yes and no. They create UV rays, which can cause cancer, but its debatable if black lights are that powerful. Black light, or near-ultraviolet light, is not harmful at a distance. Some sources might have enough short-wave UV to be harmful at short distances over a long period.
What is the difference in percentage of the UV rays to the moon in comparison to the earth?
Of the total UV rays , the moon absorbs 96.2% of the sun's UV, we get only 3.8%.
