James Clerk Maxwell FRS FRSE (13 June 1831 – 5 November 1879) was a Scottish physicist and mathematician [1] who was responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon.
This amount of energy is different for each metal. If the energy of the light quanta is less than the work function, then it does not carry sufficient energy to remove the electron from the metal. The threshold frequency, f 0, is the frequency of a light quanta whose energy is equal to the work function: =.
Michael was born in the autumn of the following year, the third of four children. The young Michael Faraday, having only the most basic school education, had to educate himself. [11] At the age of 14, he became an apprentice to George Riebau, a local bookbinder and bookseller in Blandford Street. [12]
1894 – Paul Drude introduces the symbol c for speed of light in vacuum. 1895 – Hendrik Lorentz corrects his 1892 model, proposing a contraction by the Lorentz factor (γ). 1895 – Albert Einstein probably makes his thought experiment about chasing a light beam, later relevant to his work on special relativity.
He was the greatest scientist of modern India and one of the greatest intellects our country has produced in its long history. His mind was like the diamond, which he studied and explained. His life's work consisted in throwing light upon the nature of lights, and the world honoured him in many ways for the new knowledge which he won for science.
Scientists stand ready to manipulate quantum light, just as Albert Einstein envisioned in 1916. Researchers from the University of Sydney and the University of Basel successfully managed to ...
