Photobiology
Photobiology
Photobiology (pronounced: /ˌfoʊtoʊbaɪˈɒlədʒi/) is the scientific study of the interactions of light (technically, non-ionizing radiation) and living organisms. The term is derived from the Greek words φῶς (phōs), meaning "light", and βίος (bios), meaning "life".
Etymology
The term "Photobiology" is a combination of two Greek words: "photo-" meaning light and "-biology" meaning the study of life. It was first used in the late 19th century to describe the study of the effects of light on living organisms.
