The nature of anode rays depends upon __________.

The properties of anode rays depend upon the nature of the gas taken in the discharge tube. Electric and magnetic forces cause anode rays to be refracted. They are made up of positively charged particles because they are deflected in the direction of the negatively charged plate. 

The type of gas used in the discharge tube affects the anode rays' characteristics. Positive rays of various sorts, produced by various gases, comprise particles with a range of masses and charges. Anode rays move straight forward. The particle's mass is equal to the gas's atomic mass inside the discharge tube.
