So this seems to be a feature of ultraviolet rays hitting the skin.

Ultraviolet (UV) light is electromagnetic radiation with a wavelength from 400 nm to 10 nm, shorter than that of visible light but longer than X rays.

Various types are available, for example opaque (for UV resistance and possible reduced algal growth), transparent (for esthetics), heavy and solid (for wind resistance), light and inflatable (for ease of handling).

This spacecraft was designed to observe gamma rays, X rays and UV radiation from solar flares during a time of high solar activity and solar luminosity.

So we put patients with these subjects under the UV, and their NO levels do go up, and their blood pressure goes down.

Even higher frequencies exist, such as that of gamma rays, which can be measured in exahertz.

Now, what we were careful to do was, vitamin D is made by ultraviolet B rays and we wanted to separate our story from the vitamin D story.

Mutagens include oxidizing agents, alkylating agents and also high energy electromagnetic radiation such as ultraviolet light and X rays.

The primary objectives were round the clock observations of the celestial sphere in ultraviolet and X ray spectral wavelengths with the ASTRO 1 observatory, consisting of four telescopes Hopkins Ultraviolet Telescope (HUT) Wisconsin Ultraviolet Photo Polarimeter Experiment (WUPPE) Ultraviolet Imaging Telescope (UIT), mounted on the Instrument Pointing System (IPS).

In fact, stellar electromagnetic radiation spans the entire electromagnetic spectrum, from the longest wavelengths of radio waves through infrared, visible light, ultraviolet, to the shortest of X rays, and gamma rays.

And when we shone UV at them, or when we warmed them up to the same level as the lamps, but didn't actually let the rays hit the skin, this didn't happen.

This radiation is emitted across the electromagnetic spectrum, almost uniformly, from X rays to the far infrared with a peak in the ultraviolet optical bands, with some quasars also being strong sources of radio emission and of gamma rays.

And what we've shown is that doing a sham irradiation this is the thick line here this is shining UV on the arm so it warms up but keeping it covered so the rays don't hit the skin.

Under UV light

Insects see green, blue and ultraviolet, and they see various shades of ultraviolet.

Then there's ultraviolet light.

Ultraviolet astronomy Ultraviolet astronomy refers to observations at ultraviolet wavelengths between approximately 100 and 3200 Å (10 to 320 nm).

Snow reflects ultraviolet light.

An x ray spectrometer, an x ray telescope, cosmic ray detectors, and a laser device were also included.

Lightning can be dangerous.

What the hell was that?!

Electromagnetic waves can be characterized by either the frequency or wavelength of their oscillations to form the electromagnetic spectrum, which includes, in order of increasing frequency and decreasing wavelength radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X rays and gamma rays.

The palimpsest is now stored at the Walters Art Museum in Baltimore, Maryland, where it has been subjected to a range of modern tests including the use of ultraviolet and light to read the overwritten text.

However, as ultraviolet light is easily absorbed by interstellar dust, an appropriate adjustment of ultraviolet measurements is necessary.

Lightning can be dangerous.

It uses X rays, X ray beams, that are rotating very fast around the human body.

Even higher frequency waves are called X rays, and higher still are gamma rays.

Even hard X rays and gamma rays can be reflected at shallow angles with special grazing mirrors.

the paper itself does not glow .

The electromagnetic spectrum can be divided into many different ranges such as visible light, infrared or ultraviolet radiation, radio waves, X rays and so on, and each of these ranges can in turn be divided into smaller ranges.

Radiation Radiation burns may be caused by protracted exposure to ultraviolet light (such as from the sun, tanning booths or arc welding) or from ionizing radiation (such as from radiation therapy, X rays or radioactive fallout).

Bigger objects have bigger Schwarzschild radii.

A small current is passed through that ionized air.

A convex hyperbolic mirror will reflect rays emanating from the focal point in front of the mirror as if they were emanating from the focal point behind the mirror.

The GHRS was a spectrograph designed to operate in the ultraviolet.

If you live up here, in summer the sun is coming fairly directly down, but in winter it's coming through a huge amount of atmosphere, and much of the ultraviolet is weeded out, and the range of wavelengths that hit the Earth are different from summer to winter.

Smaller objects have smaller Schwarzschild radii.

There was thunder and lightning last night.

Ultraviolet rays can cause skin cancer.

Cathode rays are beams of electrons.

Damn, the elephants are blocking my way!
