CINCINNATI, OH (FOX19) - By: University of Cincinnati Journalism Department student Jamie Gregory. University of Cincinnati Electronic Media Division student William Wolkoff contributed. A 2013 city ...

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 ...

In a flash: artist's impression of the photoelectric effect. (Courtesy: Technical University of Vienna) Just 45 quintillionth of a second (45 attoseconds) is all it takes for a photon to liberate an ...

In 1905, Albert Einstein showed that the photoelectric effect—the ability of metals to produce an electric current when exposed to light—could be explained if light is quantum, traveling in discrete ...

Sensors adhering to through-beam, diffuse, or retro-reflective sensor principles offer you choices to optimize performance in various environmental and ambient lighting conditions. Demanding ...

What's behind the target can make a tremendous difference in how well reflective sensors do their job. Consider a photoelectric sensor operating in simple diffused mode (i.e., as a proximity sensor).

With a presence in over 500 clinics around the world, Xstrahl have drawn upon their vast clinical expertise to develop a revolutionary system that has been specifically designed for the treatment ...

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light pulses. This is thanks to a new measurement technique ...

European researchers have made a laboratory-scale photoelectric panel which, apart from fulfilling the function of converting solar light into electricity, solves the problems of integratability and ...

Cooking is the leading trigger for home fire alarms, yet the device you rely on to protect your family can become so annoying near the kitchen that you are tempted to silence it or take it down. The ...

This photoelectric smoke detector circuit uses one LED and 2 LDRs to detect the smoke and sound an alarm. The LM1801 IC is the best choice for this circuit because we need a few external components ...
