    Introduction In the field of physics, the work function is a fundamental concept related to the behavior of electrons in a material. It represents the minimum energy required to remove an electron from a solid to a point in the vacuum immediately outside the solid surface. Definition and Expression The work function () is defined…

    11.1 Introduction to the Photoelectric Effect The photoelectric effect is a phenomenon where light shining on a material causes the emission of electrons. This effect played a crucial role in the development of quantum mechanics, as it provided evidence for the particle-like nature of light and led to the concept of photons as discrete packets…

    Introduction The photoelectric effect is a phenomenon in quantum physics in which electrons are ejected from the surface of a material (typically a metal) when light of a certain frequency or higher is shone upon it. This discovery provided key evidence for the quantum nature of light and was explained by Albert Einstein in 1905,…
