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 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."
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.

a narrow projection of light energy radiating from a sourse into a beam
A collection of rays of light is called a beam or a ray bundle.
The light that a torch gives out is typically called a beam or a beam of light.
