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.

No, light is not an example of matter. It is an example of electromagnetic waves. However, it is considered that light is composed of photons (massless particles) and it is applied to it some theories of matter.
A coherent beam refers to a beam of light in which the electromagnetic waves are in sync and have a constant phase relationship. This results in the waves reinforcing each other, producing a single, strong beam of light. Lasers are an example of a coherent beam source.
Yes, the sunlight passing through a mist or fog showing a beam of light is an example of the Tyndall effect. It occurs when light scatters in all directions by particles in a medium, making the beam of light visible.
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."
Any light can burn out, no matter how unlikely it may be that both low beam lights cease working simultaneously.
Light is an example of something that is not matter. Light consists of photons, which are massless particles that do not take up space and do not have mass, making them distinct from matter.
Gravity is a main thing that is not matter.
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.
