Question

For the study of particles, discharge tube is filled with:

Options
  • A

    Gas.

  • B

    Air.

  • C

    Vapours of a substance.

  • D

    All of these.

Explanation

The discharge tube can be filled with air. It can also be filled with the vapor of a substance, such as mercury vapor, in addition to gas at low pressure. When an electric current is passed through the tube, the gas inside the tube ionizes and emits light. This light is used to study the properties of particles.
