Solution

The correct options are
B They produce fluorescent discharge through the walls of the tube
C They can affect photographic plate
D They produce heating effect
Some of the properties of cathode rays are:
1. They travel in straight lines not affected by the position of the anode.
2.They possess energy by the virtue of their mass and velocity.
3.Since they are negatively charged particles, they get deflected to the anode.
4. They produce fluorescence on the surface on which they are incident.
5. During their transit they produce heating effect as they posses high kinetic energy.
