Overview
The photoelectric effect occurs when light shines on a material and causes electrons to be ejected. It was explained by Albert Einstein using the concept of photons (light quanta).
💡
Pro Tips
If the photon energy is less than the work function, no electrons are ejected.
The kinetic energy of ejected electrons depends on the frequency of light, not its intensity.
Work function (φ) is the minimum energy required to remove an electron from a material.

Fun Facts
"Einstein won the Nobel Prize for his explanation of the photoelectric effect, not for Relativity."
"The effect is the working principle behind solar panels and digital camera sensors."
"Shorter wavelengths (higher frequencies) result in more energetic electrons."
