Focal length in water
WebThe focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. WebFocal length is the system used in photography to describe how wide or tight a lens is. Listed as a number and measured in millimetres — e.g., 35mm, 85mm — it tells you how much of a scene a lens can capture, and how big subjects will appear. The number gives an indication of the angle of view that a lens can see.
