Each one is called ray and group of them is called beam.
A straight-line beam of light is commonly known as a laser. Lasers can range from weak beams, used for map pointers and leveling tools, to powerful beams such as those used in industrial cutting and medicine.
Beam is a ray or collection of parallel rays emitted from the sun or other luminous body; as, a beam of light, or a group of nearly parallel lines of electromagnetic radiation in Antenna technologies.
It is a type of ray that travels in a straight line without bending. Eg Search light,car and motor car,disco ray,sun ray and x_ray,radioactive rays.
A narrow beam of light traveling in a straight line would be a light beam.
a parallel beam of light is light that is paralled to each other
A light beam is a beam of light.
a light ray or a laser == ==
something that comes from the sun
A beam is a ray or shaft of light
A beam of light becoming dimmer is a physical change since it is reversible. Recharging its source will make the light beam bright again.
a beam of light can be seen if it passes through reflective material.
Beam spreading is when the sun's rays (or angles) spread out because the earth is in it's revolution and rotation. However this is the definition of beam spreading relating light and the amount of light received to earth, not relevant to another meaning. So basically beam spreading is when the sun's light spreads on earth.
The cop shined his flashlight so that the beam of light hit the criminal's face.
The beams of the Sun has reached the Earth's surface.
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.
Another name for light beam is ray of light. Other similar names are beam of light, shaft of light, and irradiation.
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.

A beam of light is made up of a stream of many photons.
