The photoelectric effect is a phenomenon where light knocks electrons out of a material, resulting in the emission of these electrons, called photoelectrons. Albert Einstein explained the ...

According to quantum mechanics, our universe is like a Lego set. All matter particles, as well as particles such as light that act as messengers between them, come in discrete blocks of energy. By ...

The photoelectric effect, a cornerstone of quantum mechanics, reveals the particle-like nature of light and its interaction with matter. This phenomenon, where electrons are emitted from a material ...

What is the purpose of light? How does light work? Why does light exist? This video explores the longstanding debate over whether light is composed of particles or waves. Albert Einstein demonstrated ...

Plasmon-assisted electrocatalysis provides a powerful strategy in efficient conversion of solar energy to chemical energy by combining solar light with an electrochemical bias on the plasmonic metal ...
