how far does red light penetrate water

Answers

Answer 1

Shorter wavelength, higher energy light, like blue, can penetrate further. Blue light can still reach depths beyond 40 m even if saltwater has absorbed almost all of the red visible light at this point.

what is wavelength?

Red light is more readily absorbed by water than other visible wavelengths and has a modest energy advantage over infrared light that cannot be seen. Due to this, red fish at a depth of 20 meters appear almost black. Compared to lower wavelength light, longer wavelength light is absorbed more quickly. The region of the electromagnetic spectrum that can be seen by the human eye is known as the visible light spectrum. Visible light is the more straightforward term for this set of wavelengths.

This is the main link in the hydrological cycle that delivers atmospheric water to  Earth. Most precipitation falls in the form of rain. The most normal types of precipitation are rain, hail, and snow. Rain is precipitation that falls on the surface of the earth in the form of water droplets. Raindrops form around microscopic cloud condensation nuclei such as:  Dust particles or pollutant molecules.  Weeks of  heavy rainfall  mean that catchments reach saturated capacity  quickly after storms.
