Which of the following is not a characteristic of anode rays?

The rays that consist of a stream of fast-moving positively charged particles known as protons are called anode rays. The characteristics of these anode rays are as follows:

• Anode rays travel in a straight line.
• They get deflected from their path by electric and magnetic fields in a direction opposite to the cathode rays.
• They can penetrate through thin metal foils and can ionize gases.
• The charge-to-mass ratio of these rays is very low.

So the incorrect property is - The charge-to-mass ratio of anode rays is high.
