Question

Why deep water appears green in colour ? {Colorful world, Class X}​

Answer 1

Answer:

The colours having longer wavelength are absorbed by water than those having shorter wavelengths. Red, orange, yellow, and green having longer wavelengths are absorbed by water molecules quickly when sunlight hits water. ... Thus, we can see water in blue colour in the deep sea.

Answer 2

The water appears green in colour due to the scattering of light.

• Water molecules often soak up direct sunlight and disperse distinctive colours.
• Higher waveform colours are naturally absorbed by water more quickly than lower colours.
• When sunlight strikes the water, the higher wavelength shades are swiftly taken up by water molecules.
• The higher wavelength pigments are easily taken up by water molecules when sunshine hits the water.
• These pigments are not consumed by water; rather, they are dispersed. As a result, the deep waters are bluish in colour.
• This won't be the case, though, if the water, in addition, contains algae, plants, and other contaminants, in which case the colour may alter due to light reflected by such impurities.
