Astronomers have just spied a black hole with a mass 1 billion times the sun's hurtling toward our galaxy. But scientists aren't worried about it making contact: It's some 8 billion light-years away from Earth and traveling at less than 1% the speed of ...
solar cells are photovoltaic cells that convert the sun's energy into electricity through what is termed the "photoelectric effect." This effect describes the ability of matter to emit electrons when light energy in the form of photons is supplied to ...
APD Avalanche Photodiode (APD) is a highly sensitive semiconductor electronic device that exploits the photoelectric effect to convert light to electricity. APDs can be thought of as photodetectors that provide a built-in first stage of gain through ...
In 1921, he received the Nobel prize in physics, specifically for his discovery of the law of the photoelectric effect. In a 2012 interview with Gourmet, Pi Day creator Larry Shaw said the fact that Einstein's birthday is also March 14 didn't even ...
He developed the theory of general relativity and advanced the law of photoelectric effect. His work earned him a Nobel prize in 1921, and in 1999, the Time Magazine named him "Person of the Century.
ON THIS DAY IN 1951, the Brooklyn Daily Eagle published an article titled "Four Accused of Dope Sales Taken in Trap." The article focused on four people who were arrested after trying to sell an undercover police officer drugs in Williamsburg.
My headline may be a bit misleading. Albert Einstein, the Nobel prize-winning physicist who gave the world the theory of relativity, E = mc2, and the law of the photoelectric effect, obviously had a special brain. So special that when he died in ...
Philipp Lenard (1862-1947) was a German experimental physicist who advanced the study of X-ray tubes, the photoelectric effect and atomic theory. His results led him to propose (correctly) that most of the atom is composed of empty space. Lenard was a ...
The technique uses the photoelectric effect to directly measure the momentum of electrons within each layer and shows how this changes when the layers are combined.
The American experimental physicist was honoured with the Nobel prize for physics in 1923 for the measurement of the elementary electronic charge and for his work on the photoelectric effect. More In. Related Articles. << Previous Story. Next Story >>.
His greatest achievements include mass-energy equivalence and law of the photoelectric effect. Einstein died at the age of 76 years due to internal bleeding caused by the rupture of an abdominal aortic aneurysm.
X-ray Photoelectron Spectroscopy uses photoelectric effect created by x-rays. X-rays converge on the sample surface and the energy distributed by the electrons ejected from the sample surface is probed, a process known as irradiation.
Everyone ignored Planck - presumably because they couldn't understand him - until Einstein realised that, in a photoelectric effect, high intensity light did not result in electrons being knocked free with more energy, just more electrons being knocked ...
Light falling on the pixel converts to charge by the photoelectric effect. The charge accumulates in the well and is then pushed from well to well until it reaches circuitry that measures the amount of charge and produces a digital representation of it ...
In 1905, in his capacity as editor of Annalen der Physik , he read and approved the publication of Einstein's paper on the photoelectric effect, which explained another physics puzzle by assuming that light was actually emitted in discrete bundles with ...
The discovery of photoelectric effect also provided knowledge of photocells. You can see these photocells in modern solar panels; It's one of the new green ways to make electricity on the commercial basis.

But in 1905, Einstein showed that the way some metals expel electrons when light shines on them - the photoelectric effect - could also be explained by assuming that light is made of discrete particle-like quanta, which he called photons.
In 1905 Albert Einstein described how this process worked - via the broader photoelectric effect - eventually winning a Nobel prize.

German physicist Heinrich Hertz first observed the photoelectric effect, where light is used to free electrons from a solid surface (usually metal) to create power.
Bose was close on the heels of Einstein who explained the photoelectric effect in 1905, only four years after Bose observed it in lead sulphide (galena).
Unveiled in 1979, the sculpture by Robert Berks shows the German-born physicist holding a piece of paper that carries three equations - those for the theory of general relativity, the photoelectric effect and the equivalence of energy and matter (E=mc2).
Einstein himself had inadvertently set the wheels in motion for this new area of research when he published his 1905 paper (which won him the Nobel prize in 1921) describing the law of the photoelectric effect, where light was first described as a ...
