Cathode rays rotate a light paddle placed in their path.This shows that cathode rays
The correct option is C Are made up of material particles
Explanation for the correct answer
Option C
Cathode rays consist of material particles and possess energy: This was proved by the fact that when a light paddle wheel was placed in the path of cathode rays, it was set into motion by cathode rays.
Explanation for the incorrect answers
Option A
Cathode rays consist of negatively charged particles: When cathode rays are subjected to an electric field, they get deflected towards a positively charged plate.
Option B
Cathode ray is made up of electrons, so it is not an electromagnetic wave.
Option D
Cathode rays travel in straight lines: This was proved by the fact that when a solid object was placed in the path of cathode rays, a shadow of the object was obtained.
Conclusion: Hence option C is correct.
