I believe you are actually asking the wrong question, if you are referring to a ray of light. From the viewpoint of classical physics (which designates radiation as a wave), there is no comment on the length. Given that radiation travels at the speed of light (c =~ 3*10^8 m/s) the length of a ray could be the duration of the source (in seconds) times the speed of light. However, in quantum mechanics, radiation is composed of discrete particles, called photons. Photons are massless, and there is no comment on the length, or geometry of a photon.
very long...
Its as long as his hair lol<3
Passed his shoulder
its about 4 or 3 feet long i think
people like ray ray because he got long hair and he is cute
