The particular words used to describe the item, although ray seems to me to be one thing while a beam might be several things working together.
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.
Another name for light beam is ray of light. Other similar names are beam of light, shaft of light, and irradiation.
It reflects with the angle of incidence (angle between the original ray of light and the normal (90 degrees to the mirror surface)) being the same as the angle of reflection (angle between the reflected ray of light and the normal). Some of the light energy is transferred into heat energy by the mirror, so the reflected beam is less bright than the original beam, but the difference is barely noticeable on a clean mirror.
A ray.

A beam is a general term, a ray is a vector having both direction and angular displacement.
A ray is a narrow beam of light.
ray as in a ray of light
Another name for light beam is ray of light. Other similar names are beam of light, shaft of light, and irradiation.

Each one is called ray and group of them is called beam.
A ray.
Doesn't work, it'd be like trying to shine a beam of light onto a beam of light.
A verb with a meaning 'to shine with a sudden light' is illuminate.
A flicker, a beam, a ray.
