"A beam of luminous hydrogen canal rays has, owing to its velocity, exactly the same direction as that of the electric field in which it may be made to move"

This quote by Johannes Stark is referring to the habits of a beam of luminous hydrogen canal rays when positioned in an electric field. The beam of luminous hydrogen canal rays is composed of particles that move at an extremely high speed. When placed in an electrical field, the instructions of the beam is the same as the direction of the electric field. This is due to the truth that the particles in the beam are moving so rapidly that they are able to keep up with the electric field. This phenomenon is called the Stark result. The Stark impact is a fundamental part of understanding the habits of particles in electric fields and has actually been used in numerous scientific experiments. The quote by Johannes Stark is a reminder of the value of comprehending the behavior of particles in electrical fields and how they engage with each other.
