Cathode rays:
- Cathode rays are the stream of high-speed negatively charged particles moving from cathode to anode in a discharge tube.
Properties of Cathode Rays:
- Cathode rays travel in a straight line.
- They are streams of fast-moving electrons.
- Cathode rays heat up the material on which they fall.
- The cathode rays in the discharge tube are the electrons produced due to the ionization of gas and that emitted by the cathode due to the collision of positive ions.
- Cathode rays are emitted normally from the cathode surface. Their direction is independent of the position of the anode.
- Cathode rays are deflected by an electric field and also by a magnetic field.
- Cathode rays ionize the gases through which they are passed.
- Cathode rays can penetrate through the thin foils of metal.
