Photoelectric Effect. Electrons (photoelectrons) are emitted from a metals’ surface when light of a certain frequency shines on the surface. Increased intensity results in more electrons being ejected from the metal’s surface. (Example: a solar calculator converts the energy of …

Aug 05, 2013 · These are the equations for mechanical work, power, and energy. Later on in the course there will be other equations for energy as well, especially electrical potential energy and the maximum kinetic energy an electron can have after its been knocked out of the surface of a metal (the old photoelectric effect). But rest easy, we’ll get there.

How do we know that light behaves like a particle? The photoelectric effect leads us to this. How does your solar-powered calculator work? Solar PV cells (photovoltaic) convert the energy in light to electric energy (DC current). The same principles that allow a solar-powered calculator to work also act in your cell phone’s digital camera.

Measuring Planck’s Constant Using the Photoelectric Effect
The photoelectric effect was first explained by Albert Einstein in 1905. When a light of high enough frequency is shone on a metal, electrons are ejected from the metal. According to Einstein’s explanation, when a photon hits the metal, the electrons will be ejected from the metal with a range of kinetic energies from 0 J up to some maximum ...

For the photoelectric effect to occur the threshold frequency must be met. Think of breaking a window….a ping pong ball could hit a window hundreds of times without damage but a baseball hitting the window one time will break it because the force is enough to break the window…in the photoelectric effect a beam of light with the correct ...
