Is there any quantitative relationship between luminous intensity of monochromatic light and flux of photons(number of photons/(area*second)) ?
Luminous intensity is a measure of the amount of light emitted from a source in a certain direction. It is measured in units called candelas (cd).
Luminous intensity refers to the amount of light emitted in a specific direction, while luminous flux refers to the total amount of light emitted from a source in all directions. Luminous flux is measured in units called lumens (lm).
Luminous intensity is a measure of the concentration of light in a specific direction, while luminous flux is a measure of the total amount of light emitted. The two are related by the solid angle, which represents the area of the sphere that the light is distributed over.
Photons are the basic units of light and are responsible for carrying luminous flux. The luminous intensity of a source is determined by the number of photons emitted in a specific direction, while the luminous flux is determined by the total number of photons emitted in all directions.
Luminous intensity is typically measured using a photometer, which measures the amount of light in a specific direction. Luminous flux can be measured using a radiometer, which measures the total amount of light emitted from a source in all directions.
