Which of the following statements is not correct about the characteris...
The correct answer is Option 4: Characteristics of cathode rays depend upon the nature of gas present in the cathode ray tube. Cathode rays do not depend on the material of electrode and nature of the gas that is filled in the discharged tube. However, the e/m ratio of the charge to mass of the particle is different in the case of anode rays and is dependent on the material of the electrode and the gas present in the discharged tube.

Which of the following statements is not correct about the characteris...
Characteristics of Cathode Rays
Cathode rays are a stream of negatively charged particles that are produced in a cathode ray tube. The characteristics of cathode rays are as follows:
a) They start from the cathode and move towards the anode.
b) They travel in a straight line in the absence of an external electrical or magnetic field.
c) Characteristics of cathode rays do not depend upon the material of electrodes in the cathode ray tube.
However, option D stating that the characteristics of cathode rays depend upon the nature of gas present in the cathode ray tube is not correct.
Explanation:
The nature of the gas present in the cathode ray tube affects the properties of cathode rays. The cathode rays are produced when a high voltage is applied across the electrodes in the cathode ray tube. The gas present in the tube gets ionized due to the high voltage, and the electrons are accelerated towards the anode. The properties of cathode rays are affected by the type of gas present in the tube. For example:
1. The velocity of cathode rays depends on the nature of the gas present in the tube.
2. The deflection of cathode rays in the presence of an electric or magnetic field depends on the nature of the gas present in the tube.
3. The color of the glow produced in the tube depends on the nature of the gas present in the tube.
Therefore, option D is not correct as the characteristics of cathode rays depend on the nature of the gas present in the cathode ray tube.
