Incorrect Statement for Anode Ray:
There are three correct statements about anode rays mentioned in the options provided. Let's identify the incorrect statement and explain it in detail.
Statement: The e/m ratio of anode rays is constant.
Explanation:
- Deflection by electric and magnetic fields: Anode rays are deflected by electric and magnetic fields, which is a characteristic behavior of charged particles in the presence of these fields.
- Dependence on gas in the discharge tube: The e/m ratio of anode rays actually depends on the nature of the gas in the discharge tube used to produce the anode ray. Different gases will have different e/m ratios for the anode rays.
- Production by ionization of gas: Anode rays are indeed produced by the ionization of the gas in the discharge tube, leading to the formation of positively charged ions that constitute the anode ray.
Incorrectness of the Statement:
The incorrect statement in the options is that the e/m ratio of anode rays is constant. This is not true as the e/m ratio of anode rays varies depending on the type of gas in the discharge tube. Different gases will result in different e/m ratios for the anode rays, making this statement inaccurate.
In conclusion, the correct statements about anode rays include their deflection by electric and magnetic fields, dependence on the gas in the discharge tube for their e/m ratio, and their production by the ionization of the gas. However, the statement claiming a constant e/m ratio for anode rays is incorrect.
