- When the air is colder (it easily gets -40  degrees up there) and the fuel air mixture is burned, the air  expands alot more than if warm air was entering the engine. On a  warm day a jet will not perform nearly as well as on a cold  day.2 people found this useful.hen the air is colder (it easily gets -40  degrees up there) and the fuel air mixture is burned, the air  expands alot more than if warm air was entering the engine.

Fluorescent Minerals Fluorite typically glows a blue-violet color under shortwave and longwave light. Some specimens are known to glow a cream or white color. Many specimens do not fluoresce. Fluorescence in fluorite is thought to be caused by the presence of yttrium, europium, samarium [3] or organic material as activators.

Light-emitting diode In general, a flat-surface uncoated LED semiconductor chip will emit light only perpendicular to the semiconductor's surface, and a few degrees to the side, in a cone shape referred to as the light cone, cone of light, or the escape cone. The maximum angle of incidence is referred to as the critical angle.

Jet stream What direction does the jet stream flow. The jet stream flows from west to east. Jet streams are fast flowing, relatively narrow air currents found in the atmosphere around 10 kilometers above the surface of the Earth. They form at the boundaries of adjacent air masses with significant differences in temperature, such as the polar region and the warmer air to the south.

- The Wittle jet engine: An interesting design, if they can make it run. But an axial jet was always more efficient than a centrifugal jet, and so the Bladon micro jet will probably still be more efficient than this new design. Note the pencil near the Bladon engine – the diameter of the intake is only about 18cm.

Laser Divergence Optotronics handheld laser products have a divergence spec. of 1.2mrad orless (unless otherwise noted). Most other suppliers of handheld laser products have a divergence spec. of 1.5mrad. This means that for the same beam diameter and output power, the light intensity or irradiance (Output power / area of beam spot) is up to 56% greater with a divergence of 1.2mrad vs 1.5mrad.

Absorption and Emission Lines The light that the hydrogen cloud absorbs shows up as dips in the cloud's spectrum. If the cloud were too hot, however, all its hydrogen atoms will crash into each other with enough force to free their electrons, and the gas will become ionized.

- 360-Degree Laser Welding. Precision welding by DENSO’s state-of-the-art 360-degree laser welding technology allows the Iridium TT’s twin tips to deliver omni-directional ignition, contrary to the flat “sandwich” ignition offered by other spark plugs in the market.

- Infrared’s place in the world Human eyes are sensitive to visible light: red, orange, yellow, green, blue, and violet light and all of the shades in between. However, visible light accounts for only a small portion of the total light in the universe. Radio waves, x-rays, and microwaves are all types of light.

- It also shows that the black body emits at a peak wavelength, at which most of the radiant energy is emitted. At 5000K the peak wavelength is about 5x10-7m (500nm) which is in the visible light region, in the yellow-green section.

- Discharge lamps: A quick check of the wavelength accuracy of a spectrophotometer can be performed by observing the strong emission band at 656.1 nm or 486.0nm produced by the D2 lamp.In fact many of modern, so-called self calibrating instruments make use of deuterium emission lines to set the wavelength scales.ischarge lamps: A quick check of the wavelength accuracy of a spectrophotometer can be performed by observing the strong emission band at 656.1 nm or 486.0nm produced by the D2 lamp.In fact many of modern, so-called self calibrating instruments make use of deuterium emission lines to set the wavelength scales.

- The most powerful electromagnetic radiation that reaches the retina is blue light. Blue light waves are 400 – 500 nm in wave length and are (obviously) recognized by our eye as the color blue. So when you see the blue ocean and the blue sky, you are getting hammered by blue light.

Radiation Basics Non-ionizing radiation, such as that emitted by most lasers, is different because it does not create ions when it interacts with matter but dissipates energy generally in the form of heat. The radiation associated with GTCC LLRW is ionizing radiation.

What is a Jet Stream? Jet streams are typically active at 20,000 feet (6,100 meters) to 50,000 feet (9,144 meters), or about 7 miles (11 kilometers) above the surface and travel in what is known as the troposphere of Earth’s multi-layered atmosphere.

Jet fuel Jet fuel, aviation turbine fuel (ATF), or avtur, is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colourless to straw-colored in appearance.et fuel is a mixture of a large number of different hydrocarbons. The range of their sizes (molecular weights or carbon numbers) is restricted by the requirements for the product, for example, the freezing point or smoke point.

- For a jet going slower than the speed of sound, the engine is moving through the air at about 1000 km/h (600 mph). We can think of the engine as being stationary and the cold air moving toward it at this speed. A fan at the front sucks the cold air into the engine and forces it through the inlet.

How does light from a laser differ from an ordinary light? Monochromatic. The light emitted from a laser is monochromatic, that is, it is of one wavelength (color). In contrast, ordinary white light is a combination of many different wavelengths (colors).oherent. The light from a laser is said to be coherent, which means the wavelengths of the laser light are in phase in space and time. These three properties of laser light are what make it more of a hazard than ordinary light.

- The majority of stars emit most of their electromagnetic energy as visible light, the tiny portion of the spectrum to which our eyes are sensitive. Because wavelength correlates with energy, the color of a star tells us how hot it is: red stars are coolest, blue are hottest.

- This type of activity is also detected on real comets, where the jets can sometimes expel sufficient quantities of gas to make small changes in the orbit of the comet. After several hours, the comet will become a crater-filled ice ball as the more volatile carbon dioxide sublimates before the water ice melts.

Why Are There Blue and Green Flames? This light is given off by specific atoms or molecules at specific wavelengths, and no others. This is called an emission spectrum. Blue and green flames, it turns out, have an emission spectrum. But they don't contain copper, barium, cesium, or any of the other elements that burn to give off blue or green light.
