Einstein's photoelectric effect work found that the incident light involved in the photoelectric effect was made of individual quanta (photons) that interacted with the metal's electrons like discrete particles, not waves.

Albert Einstein developed the theory of the photoelectric effect while working as a patent examiner in Bern, Switzerland in 1905. He proposed that light could be understood as consisting of particles called photons that interact with matter. This theory helped to explain certain behaviors of light that could not be explained by classical physics.

Apex Light is made of photons.
Apex Light is made of photons.
The photoelectric effect proves that light is composed of quanta called photons (packets of enegy) and therefore proves the Photon Theory composed by Einstein.
