WebJan 7, 2024 · These schemes are defined by the relation between the variance Δn and the average number n of photon counts for the corresponding distribution. Sub-Poissonian statistics: Δn < √n. Poissonian statistics: Δn = √n. Super-Poissonian statistics: Δn > √n. The Poisson distribution is characteristic of coherent light sources, such as lasers ... WebJan 9, 2024 · The number of photoelectrons emitted per unit area per unit time is directly proportional to the intensity of light used. is a correct statement. The frequency of the light is proportional to the energy of the light (through E = h f) and therefore only affects the kinetic energy of the photoelectrons coming out from the surface not their numbers.
WebPhoton is the quantum of light and light is electromagnetic wave which carries momentum and energy. i.e, If the total energy transferred to a surface in time t is U, then p=U/c . So there, is interaction of photon with matter. Take an example you can see the surrounding because photons interact with matter. Comment. WebMar 26, 2013 · Now, all we have to do is calculate the surface area (in meters) of a sphere with a radius of 16,300 light years and multiply that by the minimum 10^6 photons per second going through an area of 1 m^2 to find the minimum number of photons the star has to be emitting per second. Luckily that is not too difficult.
