Think and discuss: When the photoelectric effect was discovered, scientists were surprised that
low-frequency light was unable to remove electrons, even when the light was very bright. In other words,
scientists expected the low frequency to be offset by the light's brightness.
How does thinking about light as a stream of particles, rather than a single wave, explain this result?
