1. The term intensity, as used in the physical literature, is often used to describe the quantity that is technically referred to as irradiancein the field of radiometry. For the purposes of this study, irradiance is the quantity of interest, but intensity will be utilized occasionally as an equivalent term since that is the term used in many of the referenced studies.
