Which consequence results when electrons exceed the escape velocity of a photomultiplier tube's dynode?

💡 Explanation

Reduced signal amplification occurs because secondary electrons are not effectively collected by subsequent dynodes due to exceeding the designed kinetic energy, therefore limiting cascade gain, rather than runaway reaction with higher energies.
