The photoelectric effect is the emission of electrons from matter upon the absorption of electromagnetic radiation, such as ultraviolet radiation or x-rays. Upon exposing a metallic surface to ...

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 ...

Albert Einstein may be most famous for his theories of relativity, but he bagged the 1921 Nobel Prize for Physics for his work on the photoelectric effect. Einstein had worked out why light incident ...

The photoelectric effect is a phenomenon where light knocks electrons out of a material, ... Frequency dependence: Only photons exceeding a threshold frequency, ...

This is known as the photoelectric effect. The photoelectric effect was proposed by Hertz. After observing that electrons were ejected from an illuminated metal surface depending on the type of metal ...

The Photon and The Photoelectric Effect. ... In other words, once the frequency cutoff is met, increasing the intensity will directly increase the number of electrons coming off the metal.

The photoelectric effect can be explained with a wave model for light and a quantum model for matter ... Here h is Planck’s constant and λ is the wavelength of the light and f the frequency.

Thanks to LIGO, Pikovski says, “We not only know when gravitational waves are detected but also [their] properties such as frequency.” Data collection: The Laser Interferometer Gravitational-wave ...
