The Planck constant (also named photoelectric effect apparatus ) (cat. No 1055203) is a physical constant that is the quantum of action in quantum mechanics. Published in 1900, it originally described the proportionality constant between the energy, E, of a charged atomic oscillator in the wall of a black body, and the frequency, ν, of its associated electromagnetic wave. Its relevance is now integral to the field of quantum mechanics, describing the relationship between energy and frequency, known as the Planck–Einstein relation: With this instrument, you will be able to repeat the essential parts of the experiment that served to establish the quantum theory of radiation it also can observation that metals emit electrons when light shines upon them.(Electrons emitted in this manner may be called photoelectrons)
