Question

Which three factors are varied to examine how photocurrent behaves?

Options

• Incident radiation frequency, plate size, and tube pressure

• Applied potential, light intensity, and incident radiation frequency

• Applied potential, plate material, and tube length

• Light intensity, tube length, and window position

Answer 1

Photocurrent is examined as the applied potential, light intensity, and incident radiation frequency are varied. Each variation reveals a different feature of photoelectric emission.
