the science of quantifying the phenomena of electromagnetic radiation.
In our context, we are interested in light, the limited range of electromagnetic radiation that is visible to the human eye, sometimes extended to the areas of infrared and ultraviolet. We also don't care about the quantum mechanical aspects of radiation. It will be enough to measure the physiologically perceiveable effects. For that purpose, we will often resort to the related field of photometry.
