Deepest ray of light

Last updated: October 14, 2017 at 17:38 pm

The deepest a ray of solar light can be perceived by the human eye is 488 m (1,600 ft), or at about one-millionth of the intensity at the surface. Sunlight entering the water may travel about 1,000 m (3,280 ft) into the ocean under the right conditions, but there is rarely any significant light beyond 200 m (656 ft).
