Photoelectric in a sentence

In 1905 Albert Einstein published the theory of the photoelectric effect that firmly established the quantization of light itself. citation The chapter is an English translation of Einstein's 1905 paper on the photoelectric effect.

DHA is vitally important as it is the only fat we know of that allows your body to take advantage of the photoelectric effect, the one that Einstein received his Noble Prize for.

An increase in the intensity of the incident beam (keeping the frequency fixed) increases the magnitude of the photoelectric current, although the stopping voltage remains the same.

A solar cell is a device that converts light directly into electricity using the photoelectric effect.

Baird achieved this, where other inventors had failed, by obtaining a better photoelectric cell and improving the signal conditioning from the photocell and the video amplifier.

Cross section The photoelectric effect is one interaction mechanism between photons and atoms.

Even after experiments showed that Einstein's equations for the photoelectric effect were accurate, resistance to the idea of photons continued, since it appeared to contradict Maxwell's equations, which were well-understood and verified.

If the photon's energy is greater than the substance's work function, photoelectric emission occurs and the electron is liberated from the surface.

If we apply a negative potential to the collector plate Q with respect to the plate P and gradually increase it, the photoelectric current decreases, becoming zero at a certain negative potential.

In 1905 Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons.

In 1917 Theremin wrote that Ioffe talked of electrons, the photoelectric effect and magnetic fields as parts of an objective reality that surrounds us everyday, unlike others that talked more of somewhat abstract formula and symbols.

Intensity-dependent phenomena have now been studied in detail with such lasers. citation Einstein was awarded the Nobel Prize in Physics in 1921 for his discovery of the law of the photoelectric effect.

Joel Stebbins at the University of Illinois Observatory used an early selenium cell photometer to produce the first-ever photoelectric study of a variable star.

Millikan is also credited with measuring the value of Planck's constant by using photoelectric emission graphs of various metals.

Music was produced by a series of photoelectric cells underneath the chessboard, triggered sporadically by normal game play.

Night vision devices Photons hitting a thin film of alkali metal or semiconductor material such as gallium arsenide in an image intensifier tube cause the ejection of photoelectrons due to the photoelectric effect.

Photoelectric effect illuminated While Planck had solved the ultraviolet catastrophe by using atoms and a quantized electromagnetic field, most contemporary physicists agreed that Planck's "light quanta" represented only flaws in his model.

Photoelectric measurements require a great deal of care, as an incorrectly designed experimental geometry can result in an erroneous measurement of work function.

Quantum mechanics Photoelectric effect main In a second paper published in 1905, Albert Einstein undermined the very foundations of classical electromagnetism.

Robert Andrews Millikan studied the photoelectric effect experimentally, and Albert Einstein developed a theory for it.
