Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. It is so named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet (purple). ...
PROBLEM TO BE SOLVED: To provide a food component for preventing the degradation of health for dealing with the attack of electromagnetic waves such as ultraviolet rays to be increased corresponding to the expansion of ozone layer destruction year by year.YONEDA MINORU...
The ultraviolet (UV) sterilizer is a type of sterilizer that kills microorganisms (fungi, bacteria, etc.) and viruses. Ultraviolet rays, which are electromagnetic waves with short wavelengths, damage molecules with their high energy, thereby killing microorganisms and viruses. In particular, ultraviolet...
Unlike X-rays,ultraviolet radiationhas a low power of penetration; hence, its direct effects on thehuman bodyare limited to the surfaceskin. The direct effects include reddening of the skin (sunburn), pigmentation development (suntan),aging, and carcinogenic changes. Ultraviolet sunburns can be mi...

Ultraviolet (UV) rays are higher in energy and do not fall within the realm of visible light, as shown here. In the electromagnetic spectrum, radio waves have the lowest energy, and gamma rays have the highest energy. While many people refer to ultraviolet radiation as "UV light," this te...
The sun produces short light waves called ultraviolet rays. Lesson Quiz Course 17Kviews UV-A Rays Ultraviolet rays are often called UV rays for short, and there are three types. UV-A rays are the ones that you get exposed to every day. When you go outside during the day, you absorb ...
Ultraviolet (UV) radiation is a form of non-ionizing radiation found at the lower end of the electromagnetic spectrum between x-rays and visible light as shown inFig. 1. The categories of radiation in the spectrum are classified by their wavelength (i.e., the distance between peaks of th...
X-rays come after UV light on the electromagnetic spectrum. The UV light spectrum can be divided in a number of different ways. Scientists refer to near, extreme and far UV light, based on the wavelength of the light and how energetic it is. UVA, UVB and UVC are also used to ...
