Can Cathode Rays Be Deflected by Electric Field?

Cathode rays can be deflected by an electric field, which is evidence of it being composed of electron particles rather than photons. They are deflected by electric field towards the positive plate. when the cathode rays were passing through it; the divisions on the plate enabled the path of the rays to be determined.

Why do cathode rays deflected in electric field?

That rule describes how a charged particle (our electron) moving in a magnetic field will be deflected by that field at a right angle to both the field and to the direction of the particle. ... The electrons in the cathode rays would deflect toward the positively charged plates, and away from the negatively charged plates.

What happens when cathode rays pass through the electric field?

Cathode rays are stream of electrons. Electrons are negatively charged and they get attracted to positive potentials. ... Thus, as seen in the diagram below, if the electric field is perpendicular to the direction ofcathode ray, then the ray will deflect towards the electric field(positive side).
