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 ...

When light hits a material, electrons can be released from this material -- the photoelectric effect. Although this effect played a major role in the development of the quantum theory, it still holds ...

With a short syllabus, formula-based questions, and high predictability, Modern Physics can fetch 12–16 marks if prepared ...

The photoelectric effect refers to what happens when electrons are emitted from a material that has absorbed electromagnetic radiation. Physicist Albert Einstein was the first to describe the effect ...

June 9, 2022, marks 117 years since Einstein published his groundbreaking paper on the photoelectric principle. The analysis was published on June 9, 1905, also known as Einstein’s “miracle year” ...

Detecting gravity: Researchers have proposed an experiment that could detect the elusive graviton – a quantum of gravity – using quantum sensing. (Courtesy: Pikovski research group) According to ...
