When a telescope views a far off star, one that is said to be a light year away for example, we are seeing beams of light (and the image of that star) that have been travelling for one year at 10,000,000,000,000 kilometers per year.(10 to the 13th. power kpy) So end-on, we see the results (visible). From the side,(invisible), it's travelling too fast. So the answer depends on whether we are seeing the light beam coming toward us or if it is passing by . CursingL: If you move at the speed of light. The light, that would usually bounce of you so other people would be able to process the image with there eyes, would stay on you and never bounce off. Think about that
How absorption and scattering can affect a beam of light is if the beam of light is farther away from an object, the light would be dimmer. But, if the beam of light was closer to the object, then the light would appear brighter.
If one shines into your eye (don't do this it is dangerous) then you would see it directly. However, a lazer beam going past you would be invisible UNLESS there was a substance in its path that could reflect parts of its light back to you (such as mist or dust).

A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.
Another name for light beam is ray of light. Other similar names are beam of light, shaft of light, and irradiation.

An infrared beam is often used on a security alarm. When the beam is broken, an alarm sounds. The beam is invisible because infrared is electromagnetic radiation that has longer wavelengths than the ones with visible light.

If a beam of light strikes a perfect black body, it will be absorbed and, therefore, you will have been able to "stop light in air" as was asked. If your question is about stopping the beam and holding it in place in some way, you cannot. The speed of light is a constant, and will be found to be the same in any inertial frame. If you could measure the speed of a beam of light and were moving "along side" the beam to measure its speed, you'd find it a constant no matter how fast you were moving. Stopping a beam of light in air is not something that can be done as asked.

High beam light is out!
Since a laser beam is light all moving on the same direction, the path of a laser beam will be a straight line, inless it is redirected by a reflective surface.
transparency is a physical property of matter, and depends entirely on the which element you are taking about.
a type of light, from a beam of light
