Particle-Like Properties of Light (VCE SSCE Physics): Flashcards

Light on metal surface ejects electrons

Min. frequency needed to emit photoelectrons from metal

Energy electron gains/loses moving through 1V potential diff.

$1.6 \times 10^{-19}$ J

$E = hf$ or $E = \frac{hc}{\lambda}$

$6.63 \times 10^{-34}$ J s

$E_{k \text{ max}} = hf - \phi$

Min. energy required to release photoelectron from metal

More photoelectrons emitted, but same max. kinetic energy

Min. voltage to just stop most energetic photoelectrons
