PROPERTIES OF CATHODE RAYS

- Cathode rays always travel in straight line. Whenever an object is placed in the path of cathode rays, it casts a shadow on the walls opposite to the cathode.
- Cathode rays consist of material particles and produce mechanical effects.
- The beam of cathode rays are deflected towards the positively charged plate, hence the particles in the cathode rays carry negative charge.
- Cathode rays are also deflected from their path in magnetic field.
- Cathode rays penetrate the sheets of aluminium and other metals.
- The cathode rays produce X-rays when they strike metals with high melting point like tungsten.
- The cathode rays upon striking glass or certain other material cause them to glow.
