UV radiation is invisible to the eye and it is non-ionizing form of radiation in the 100 nm to 400 nm wavelength region of the electromagnetic spectrum. UV radiation is arbitrarily divided into UV-A ...

The point is that we generally consider light to be good, safe, even comforting. Yet when it comes to our skin, things are a ...

Spending enough time in the sun without adequate protection can leave us looking and presumably feeling like a lobster ready for the plate.

Here's a tour that begins with radio waves and takes you through microwaves, infrared radiation, light, ultraviolet radiation, and X-rays. The tour ends with gamma rays, the potentially deadly ...

Ultraviolet (UV) radiation can cause eye damage ... Each region of the electromagnetic spectrum has a range of wavelengths associated with it. The range of wavelengths affects the way each ...

In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. Electromagnetic waves ...

Extreme ultraviolet (EUV) lithography is the next step in this trend. It uses radiation of wavelength 13.5 nm, thereby offering significant potential to extend the resolution of photolithography.

“It appears that opsins signal melanocytes to make more melanin in response to UV exposure,” saysDr. Shamban. As we learn more about how light, in all its wavelengths, contributes to many of ...
