In the absence of electric or magnetic field, the cathode rays travel in straight line.

In the presence of electric or magnetic field, the behaviour of cathode rays is similar to that expected from negatively charged particles.

In the presence of electric and magnetic field, the cathode rays travel in straight line.

The cathode rays starts from the cathode and move toward the anode.
