The word 'photic' is commonly used in the context of light and its effects on living organisms. It refers to anything relating to or influenced by light, such as photosynthesis or vision. For example, "the photic zone is the area of the ocean where there is enough sunlight for photosynthesis to occur." It is not a word that is commonly used in everyday conversation, but rather in scientific or technical fields.
