Does a laser change direction in mid air?
No, a laser beam travels in a straight line through air unless it reflects off a surface. The direction of a laser beam can be altered by using mirrors or prisms, but it does not change direction on its own in mid-air.
What are 5 different types of plasmas?
Thermal plasma: ionized gas at very high temperatures, commonly used in industrial applications like welding and cutting. Nonthermal plasma: ionized gas at lower temperatures, often used in environmental applications like air purification. Astrophysical plasma: ionized gas found in stars, interstellar space, and galaxies, playing a key role in the universe's dynamics. Magnetized plasma: ionized gas influenced by magnetic fields, important in controlled fusion research and space physics. Laser-induced plasma: ionized gas created by a laser pulse, used in various fields including spectroscopy and material processing.
How can one see an invisible laser beam?
One can see an invisible laser beam by using special equipment like a laser beam detector or by observing the beam's reflection off of particles in the air.
Why cant you see the laser beam while it is traveling through the air?
Normal (non-coherent) light IS visible in air, just not too noticeably. If something is "visible" then that means specifically that "visible light" (aka light in the visible spectrm) is reaching your eyes. Lasers are only special because instead of being many wavelengths of light, they only emit one wavelength of light. And if that particular wavelength is not in your area then you will see that one more than others. Notice that a laser "tints" the wall red. If you put a red laser on a blue wall then you will see purple dot; etc.. That's why you see the sunset when the sun is no longer in view, the light being scattered by the air and the particles in the air. It's also why the sky is blue, with blue light being scattered by the atmosphere more than the red. But that aside, a low power red laser is not very visible in the air since the longer wavelength of the red light doesn't scatter well off the air molecules. Larger dust or smoke particles in the air can reflect the low power red laser and you see the twinkling effect as the beam hits the individual particles. On the other hand, a the shorter wavelength of a blue-green laser scatters off the air molecules more effectively, so you can see the photons scattering off from the beam. A very high power laser in air is another story. It has sufficient energy to ionize the air within the beam (like a lightning channel) and this ionized air glows with its own emitted light.
What does ionising air mean?
Ionizing air refers to the process of creating charged particles, or ions, within the air. This can be accomplished using devices such as ionizers or corona discharge systems, which release high-energy electrons that collide with air molecules, causing them to lose or gain electrons and become charged. Ionized air can have various applications, such as air purification or static electricity reduction.

Which term describes reattachment of a detached retina by using a laser?
Laser retinopexy is the term for reattaching a detached retina using laser therapy. This procedure involves using a laser to create burns around the retinal tear to seal it and prevent further detachment.
What is an air shower?
An air shower is an extensive cascade of ionized particles formed by the entry of a cosmic ray into the atmosphere.
Would there be any difference with an ion engine using already ionized gas instead of non ionized. ie hydrogen?
The thrust of an ionized plasma engine would be significantly greater than that of a standard oxidization engine.
Can you etch plexiglass using a laser engraving machine?
Yes, plexiglass can be etched using a laser engraving machine.
Does lightning have a solid state?
No. Lightning is an electric current flowing through ionized air.
How Does Laser Treatment for Cataracts Work?
Laser treatment for cataracts involves using a femtosecond laser, an ultra-fast and precise laser technology.
Does Ryan air take laser cards?
Ryanair accepts Laser Card again.
What has the author Frank J Bauer written?
Frank J. Bauer has written: 'Effects of ionized air and electroconvulsive shock on learning and innate behavior in rats' -- subject(s): Electric shock, Ionized air, Maze tests, Physiological effect
