The author reflects on the need for a specific definition of light in science. The author relates the definition of light from ANSI/IES RP-16-10 Nomenclature and Definitions for Illuminating Engineering, stating that it is a radiant energy. He says that light as a word and concept is employed in three ways such as physical quantity, visual response, and biological response. He adds that a casual relationships between light and human health is shown in medical studies.
