Photopõhise

Photopõhise is an Estonian term that translates to "light-based" or "photo-based." It is primarily used in the context of scientific and technical fields to describe processes, phenomena, or technologies that utilize or are initiated by light. This can encompass a wide range of applications, from photography and optics to photochemistry and photobiology.

In photography, "photopõhise" refers to the fundamental principle of capturing images through the interaction of light with a photosensitive medium, whether it be film or a digital sensor. This process involves the absorption of photons and their subsequent conversion into a visual representation. Beyond traditional photography, the term is also relevant in fields like photolithography, a critical technique in semiconductor manufacturing where light is used to pattern materials.

Photochemistry, a branch of chemistry concerned with the effects of light on chemical reactions, also falls under the umbrella of "photopõhise" phenomena. Examples include photosynthesis in plants, where light energy is converted into chemical energy, and various photochemical reactions used in synthesis and industrial processes. Photobiology studies the effects of light on living organisms, encompassing areas like vision, circadian rhythms, and the therapeutic use of light in medicine. The concept of "photopõhise" highlights the central role of light as an energy source or a trigger in these diverse scientific domains.
