Rays from the sun are very close to parallel. Rays from a more distant star will be even closer to parallel.
However, since light propagates as waves, you cannot have truly parallel beams which do not interfere.
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.
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.
A ray is a narrow beam of light.
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.

Another name for light beam is ray of light. Other similar names are beam of light, shaft of light, and irradiation.
