No. Photons, the particles that make up a beam of light, have no rest mass, so they can't be considered "matter" by any reasonable definition.
They do have a relativistic mass m = hv/c2 (that "v" should be the Greek letter nu), but that's not the same thing.
Examples of matter: water, air, iron. Non-examples of matter: light, sound, thoughts.
Magnifing glass
A beam of light is simply referred to as light or a light beam.
Another name for the beam of light from a flashlight is a "light beam" or "beam of light."
Examples of convergent beams of light include light passing through a converging lens, sunlight focusing through a magnifying glass to a point, and laser light converging to a tight spot.
Any light can burn out, no matter how unlikely it may be that both low beam lights cease working simultaneously.
One example of a parallel beam of light is sunlight reaching the Earth's surface, as the rays from the Sun are nearly parallel due to the vast distance between the Sun and Earth. Another example is laser light, which is produced by stimulated emission and consists of highly coherent and parallel rays due to the nature of the laser's construction and operation.
a type of light, from a beam of light
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.
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.
