Photon intensity formula
WebThis is also what physicists believed would happen if the light intensity was increased. Light amplitude was expected to be proportional to the light energy, so higher amplitude light … WebPhoton Wavelength Formula. By knowing the frequency of the photon, one can easily calculate the wavelength with the help of the equation λ=cν where c is the speed of light and ν is the frequency. Example: If a photon has a frequency of 6×1012s −1 the wavelength is. λ=3×108ms/ 6×1012s −1. = 5×10 −5 m=50 micrometres.

Some Definitions: Intensity and Flux The monochromatic intensity is the brightness of a beam of radiation. It is defined by the equation dE ν = I ν dA dT dν dω where dE ν is the amount of energy passing through an area dA in time dT, over a frequency interval dν, into a solid angle dω. The units of I ν are ergs …
WebDec 5, 2024 · So, when you're talking about the macro-level, AKA, a body emitting light as some of the answers here explain, Stefan's law applies. But when you're solely talking about a photon, Stefan's law doesn't apply and so.. intensity of a photon isn't dependent on temperature IN QUANTUM PHYSICS. Don't know how... that works.
