Light (also referred to in professional literature as radiation) is best thought of as a spectrum consisting of ultraviolet light (UV) at the short end, visible light in the center, and infrared (IR) wavelengths at the long end. The high energy of UV radiation is particularly damaging to artifacts.

What is the difference between UV light and infrared?
Infrared and ultraviolet radiation are two types of electromagnetic radiation. The key difference between infrared and ultraviolet radiation is that the wavelength of infrared radiation is longer than that of visible light, whereas the wavelength of ultraviolet radiation is shorter than the wavelength of visible light.
Which is more harmful UV or infrared?
When you look at the EM spectrum, UV waves are quite a bit smaller in wavelength than infrared, and x-rays/gamma rays are even smaller. Therefore, UV waves are probably causing more harm than infrared waves, and x-rays/gamma rays are probably doing even more damage.
Is sunlight UV or infrared?
The sun is a major source of ultraviolet rays. Though the sun emits all of the different kinds of electromagnetic radiation, 99% of its rays are in the form of visible light, ultraviolet rays, and infrared rays (also known as heat).
What is similar between infrared and ultraviolet?
Infrared and Ultraviolet radiations share striking similarities. For instance: They are both invisible to the human eyes and transmitted as waves consisting of changing magnetic and electric fields. The waves are self-propagating and carry a bundle of energies which are converted to heat.
Is infrared light safe?
Infrared light is delivered to the site of injury or inflammation at certain wavelengths, promoting cell repair. The key characteristic of infrared light is its ability to penetrate even the deep layers of the skin, providing better pain relief. Also, infrared light is safe, natural, non-invasive, and painless.
Which is hotter infrared or ultraviolet?
Ultraviolet radiation is more energetic than infrared. But “hotter” is a somewhat informal term. A photon of UV radiation has a lot more energy than a photon of IR, but the total energy has to take into account the number of photons as well. The heat we feel from sunlight is infrared.
Is infrared harmful to humans?
Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively. To help protect against long-term IR exposure, workers can wear products with IR filters or reflective coatings.
Is near infrared harmful?
There are, in fact, known risks to near-infrared radiation exposure. More worryingly, IR-A radiation can penetrate deeply into the skin and cause tissue damage, resulting in photoaging of the skin (Schroeder et al. 2008, Robert et al. 2015), and at worst, possibly skin cancers (e.g., Schroeder et al.
Does Near Infrared damage skin?
Second of all, the research shows that near infrared causes damage to the skin. The research shows that exposure to near infrared accelerates the aging of skin and is part of what ages a person’s skin when they spend too much time out in the sun.
How do you make a UV light?
UV radiation is produced either by heating a body to an incandescent temperature, as is the case with solar UV, or by passing an electric current through a gas, usually vaporized mercury. The latter process is the mechanism whereby UV radiation is produced artificially.
What are the 3 types of UV rays?
The most common form of UV radiation is sunlight, which produces three main types of UV rays:
Is infrared UV light?
Light (also referred to in professional literature as radiation) is best thought of as a spectrum consisting of ultraviolet light (UV) at the short end, visible light in the center, and infrared (IR) wavelengths at the long end. UV light can be measured using a UV meter.
What is infrared sauna used for?
Infrared sauna therapy helps you relax while getting an invigorating deep tissue sweat, leaving you fully refreshed, rejuvenated & renewed. Unlike traditional saunas, infrared saunas provide a gentle, soothing therapeutic heat that promotes relaxation & improved sleep.
What kind of light is infrared?
Infrared radiation (IR), or infrared light, is a type of radiant energy that’s invisible to human eyes but that we can feel as heat. All objects in the universe emit some level of IR radiation, but two of the most obvious sources are the sun and fire.
What is UV light made of?
The ultraviolet lamp usually consists of an electric discharge lamp with material that yields radiations at the desired wavelength. Ultraviolet lamps are usually housed in quartz or special glass that transmits ultraviolet radiation more readily than ordinary glass.
