He also investigated the light spectra of gases and vapours, worked on the passage of electricity through gases, and discovered new properties of cathode rays (electron rays).

Indeed, Japan could become one of the few rays of light in an otherwise gloomy advanced country landscape.

The number of the light rays in the Sun of the Presidential Seal were reduced to 16 (8 long and 8 short light rays, all of them sharp edged) in order to symbolize the 16 Turkic states in history, with another legal amendment on February 18, 1978.

The light rings are caused by constructive interference between the light rays reflected from both surfaces, while the dark rings are caused by destructive interference.

Its birth heralded the fact that cooperation and international brotherhood could bring rays of light to even the darkest of times.

Were the Earth flat, light rays that bend down would soon hit the ground and only nearby objects would be affected.

For every the light rays can travel parallel to the Earth's surface, the Sun will appear 1 higher on the horizon.

This equipment uses two types of rays x rays and gamma rays to detect objects such as weapons, bombs and other explosives, and drugs.

X Rays

Gamma Rays

I had just taken trigonometry in high school, I learned about the parabola and how it could concentrate rays of light to a single focus.

In 1876, the German physicist Eugen Goldstein showed that the rays from this glow cast a shadow, and he dubbed the rays cathode rays.

Shklovsky proposed that cosmic rays from supernova explosions within 300 light years of the sun could have been responsible for some of the mass extinctions of life on earth.

The presence of this compound in human skin enables humans to manufacture vitamin D3 from ultraviolet rays in the sun light, via an intermediate isomer pre vitamin D3.

Ultimately, other sources of illumination will have to be put to use, such as electron beams, x rays or similar sources of electromagnetic energy with wavelengths much shorter than visible light.

Since Earth is round, if their downward bending curve is about the same as the curvature of the Earth, light rays can travel large distances, perhaps from beyond the horizon.

I'll take some X rays of your teeth.

He became an assistant at the school during the period of 1894 97 when he began the study of cathode rays and X rays.

Such equipment, which will be supplied to all remaining border posts in the near future, employs two kinds of rays, namely X rays and gamma rays, and seeks such contraband items as arms, bombs, explosives and narcotic drugs.

Because these latter rays passed through the holes, or channels, in the cathode, Goldstein called them Kanalstrahlen , or canal rays.

It was not until the 20th century that science could explain the reason the real Sun had still been below the horizon, but its light rays followed the curvature of the Earth.

Sunlight is not rich in ultra violet rays, as these have been absorbed by the atmosphere, and it does not produce nearly so large an effect as the arc light.

The ultra violet light to produce these effects may be obtained from an arc lamp, or by burning magnesium, or by sparking with an induction coil between zinc or cadmium terminals, the light from which is very rich in ultra violet rays.

Each of the gamma rays has an energy of 0.511 MeV.

Many species of sharks and rays inhabit the surrounding body of water.

Those who live in the dark, are afraid of the sun's rays!!!

Cosmic rays comprise also high energy atomic nuclei, particularly that of iron.

Epsilon rays are a form of particle radiation and are composed of electrons.

The three lines from object endpoint formula_5 heading toward the eye indicate the bundle of light rays that pass through the cornea, pupil and lens to form an optical image of endpoint formula_5 on the retina at point formula_7.

He believed the rays to consist of streams of particles of ordinary molecular magnitude.

And this shows how I do my process of same size X rays.

Like all X rays, mammograms use doses of ionizing radiation to create images.

The coloring, so coloring adds another level to the X rays.

He observed tubes with energy rays extending from a negative electrode.

The hot diffuse gas in the Local Bubble emits X rays.

These rays produced a fluorescence when they hit the glass walls of the tubes.

The value of g for diagnostic x rays is only a fraction of a percent.

If the vertical temperature gradient is 12.9 C per 100 meters (where the positive sign means temperature gets hotter as one goes higher) then horizontal light rays will just follow the curvature of the Earth, and the horizon will appear flat.

Small amounts of tritium occur naturally because of the interaction of cosmic rays with atmospheric gases.

They are themselves a cause of further warming ice and snow reflect the sun s rays.

One of these buildings was a dome which allowed the sun's rays to pass through.

In most cases, x rays will be taken of both clavicle bones for comparison purposes.

Compton observed in gamma rays, which do not penetrate the lower atmosphere.

You look at your X rays on a screen and you do stuff with them, you email them. But we were still using X rays, but we didn't even have a viewing box!

The lorry goes in front of it. And it takes slices of X rays through the lorry.
