Which radiative outcome occurs when a photomultiplier tube detects pulses of light?

💡 Explanation

An electron cascade and amplified signal occurs because each photon striking the photocathode triggers secondary electron emission. This process, known as secondary emission, amplifies the signal, therefore boosting detection rather than thermal runaway that leads to diminished current output.
