The color of light that penetrates seawater to the greatest depth in coastal waters is.
Colors can be described in wavelengths. The shorter the wave, the higher the energy. We know that violet has the "highest" energy with wavelength of around mm and then blues (~), green (~) and finally reds (~). That means that when going deeper red will disappear first, then greens, blues and violet Hope it makes sense.
Light Penetration. The light that penetrates the surface is refracted due to the fact that light travels faster in air than in water. Once it is within the water, light may be scattered or absorbed by solid particles. Most of the visible light spectrum is absorbed within 10 meters (33 feet) of the water's . Each color of the spectrum has specific wavelength ranges. The colors in the middle of the visible spectrum (yellow, green and blue) penetrate seawater to the greatest depth, while colors of longer (violet) and shorter (red and orange) wavelengths are absorbed and scattered more rapidly.
Light & Color in the Ocean MarineBio T Light & Color in the Ocean The penetration of sunlight into the sea and its interaction with water and dissolved and suspended materials is an important physical phenomenon in the ocean.
Even the clearest seawater is not perfectly transparent. In the very clearest tropical waters the photic zone may extend to a depth of meters, but a more typical value for the open ocean is meters. In contrast, light typically penetrates the coastal waters in which we swim only to about 40 meters. We typically see the ocean as having a blue-green color because these are the wavelengths that penetrate the deepest and are scattered back to our eye. The upper m of the ocean is called the photic zone (photo = light). Beyond this depth, light does not penetrate, and it is pitch dark.

The colored curves on the graph above show the intensity of light (solar radiation) at different depths in the ocean plotted against wavelength of light at each depth. The colors indicate light intensity at four water depths: 0 meters. meter = slightly less than a half inch. meters=20 inches. Wavelengths in the waves. Much sunlight reflects off the ocean, but much also penetrates into it and is strongly absorbed by seawater. Several hundred miles from shore, our diver sees extraordinarily clear and pure blue water because water in the open ocean has low concentrations of dissolved matter and particles, including phytoplankton.
I was wondering about what colour of light penetrates deepest, and stumbled upon this pic while reading about related content. What penetrates deeper in water? Blue or voilet? Ask Question 0. 3 Only sea water appears blue in color, why this is not happening in river water? 0. Blue LED light source. Hot Network Questions. Jun 25, · How far does light travel in the ocean? Light may be detected as far as 1, meters down in the ocean, but there is rarely any significant light beyond meters. Only a small amount of light penetrates beyond this depth. The zone between meters ( feet) and 1, meters (3, feet) is usually referred to as the.
Since the color blue penetrates best in water, there simply are not that many blue animals in the midwater regions of the ocean; their entire bodies would reflect the blue light and they would be highly visible to predators. Seawater - Optical properties: Water is transparent to the wavelengths of electromagnetic radiation that fall within the visible spectrum and is opaque to wavelengths above and below this band. However, once in the water, visible light is subject to both refraction and attenuation.
