What is the initial behavior of electrons emitted from a heated filament?

• They move rapidly in a straight line.

• They move slowly in all directions.

• They are immediately focused into a beam.

• They are absorbed back into the filament.

How does a high positive potential (anode) affect the movement of electrons?

• It slows them down.

• It scatters them in all directions.

• It focuses and accelerates them into a beam.

• It neutralizes their charge.

What is the primary function of the anode in an electron gun?

• To convert electrons into light.

• To attract and accelerate electrons.

• To heat the filament.

• To emit electrons.

What is a cathode ray?

• A high voltage device.

• A form of light.

• A type of filament.

• A beam of electrons.

How do cathode rays differ from light?

• They are beams of electrons, not photons.

• They are slower than light.

• They are visible to the naked eye.

• They are emitted from the anode.
