Visibility is a term which generally predicts the ability of some human or instrument to detect an object in the given environment, and may be expressed as a measure of the distance at which an object or light can be discerned. The theoretical black body visibility of pure water based on the values for the optical properties of water for light of 550 nm has been estimated at 74 m. For the case of a relatively large object, sufficiently illuminated by daylight, the horizontal visibility of the … Web16 dec. 2024 · No, you cannot scuba dive to the Titanic. The Titanic lies in 12,500 feet of ice cold Atlantic ocean and the maximum depth a human can scuba dive is between 400 to 1000 feet because of water pressure.
