Photon density formula
WebAs the wave equation which we study has the character of vector, we choose wave function ψ~(~r,t) to describe the wave. The wave function ψ~(~r,t) can be calculated with relativistic wave equation and it also has statistical meaning, i.e., ψ~(~r,t) 2 can be explained as the photon’s probability density at the definite position. WebNumber density. The number density (symbol: n or ρN) is an intensive quantity used to describe the degree of concentration of countable objects ( particles, molecules, phonons, cells, galaxies, etc.) in physical space: three-dimensional volumetric number density, two-dimensional areal number density, or one-dimensional linear number density.

WebMar 6, 2024 · Blackbody radiation formulas for energy and photon density and for energy and photon plane irradiance, in spectral units of wavelength λ , frequency ν , and wavenumber ν . Formulas require wavelength in meters and wavenumber in 1/meters. Divide the E d and Q d formulas by π to obtain formulas for blackbody radiances. WebMar 19, 2012 · Yellow light has a wavelength of about 550nm. The energy of a single photon is given by E=h*c/λ, where h is Planck's constant, c is the speed of light, and λ is the photon's wavelength. Thus a 550nm photon has an energy of about 3.6*10^-19 Joules. Therefore, you would need 1300/ (3.6*10^-19)=3.6*10^21 photons to make 1300 Joules, and thus you ...
