mfb said:1.51*10-20 photons per second? I think that is a typo.
mfb said:The approach is good, and the numbers look reasonable.
Photon flux refers to the rate at which photons, which are the smallest units of light, are emitted from a light source. It is measured in photons per unit time, typically in units of photons per second.
Photon flux is directly related to the brightness of a light source. A higher photon flux means a higher number of photons are being emitted per unit time, resulting in a brighter light source.
Photon flux can be measured using specialized instruments such as a spectrometer or a photometer. These instruments can detect and measure the number of photons being emitted from a light source per unit time.
The further away from a light source you are, the lower the photon flux will be. This is because light spreads out as it travels, resulting in a decrease in the number of photons per unit area.
Yes, the wavelength of light can affect photon flux. Some light sources emit more photons at certain wavelengths, resulting in a higher photon flux at those specific wavelengths. This is why some light sources may appear brighter or more intense than others, even if they emit the same number of photons.
