why cathode rays is not travel in both directions

Answer:
We know that cathode rays cast shadows of solid objects placed in their path. During experiment performed on these rays, fluorescence (flash of light) is observed in the region, outside the shadow. This shows that cathode rays travel in straight lines. We also know that cathode rays penetrate through a thin sheet of metals but are stopped by thick sheets. Therefore assertion is false but the reason is true.
Explanation:
Properties of Cathode rays (1)They travel in straight lines away from cathode with very high velocity ranging from 1 0 7 t o 1 0 9 m/sec. The fact that the cathode rays (electrons) are deflected by electric and magnetic fields is made use of in this method.
Umm..I don't quite understand your question
Cathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube. Since the electrons have a negative charge, they are repelled by the cathode and attracted to the anode. They travel in straight lines through the empty tube
So, in conclusion: Cathode rays move towards the positively charged anode
Why on earth would they travel from the anode to the cathode?
