As a result, blue light can penetrate deeper into the ocean than red light. The depth to which light can penetrate also depends on the clarity of the water. In clear water, light can penetrate deeper than in turbid water with high concentrations of particles. The amount of light that penetrates the ocean also varies seasonally.
Red light has the lowest energy. In water, colors with lower energy, such as reds, oranges, and yellows are filtered out quickly. Because blue and violet light waves have more energy, they travel deeper through water. A view of a mussel bed near New Zealand at 100 m depth, lit only by sunlight. Note the blue color tones.

Light is energy traveling at the fastest speed in the universe through what are called light waves. Unlike ocean waves, light waves are electromagnetic energy. Like all electromagnetic energy, they have different wavelengths. Parts of a wave: 1. Crest – the highest point of a wave 2. Trough – the lowest point of a wave 3. Wavelength – the distance ...
Sunlight contains all of the colors of our visible spectrum— red, orange, yellow, green, blue, and violet (ROYGBV). When all of these colors are combined together, they appear white as white light. Each visible color has its own wavelength, or distance between two waves. Red light has the longest wavelength in the visible spectrum and violet has th...
Very little light from the surface penetrates between 200 and 1,000 meters, in what’s known as the dysphotic or twilight zone. Once we reach about 1,000 meters depth, light from above has disappeared entirely. This sunless realm is known as the aphotic zone. Light conditions affect how much both humans and organisms see. Some deep- sea organisms’ e...
The wavelength of light that reflects off an object is the color we see. For example, an object we see as red in white light appears that way because it reflects longer, less energetic red light waves. It absorbs the other colors (all of which are present in white light). Red and orange light waves have less energy, so they are absorbed near the oc...
Red and black animals are common in the deep ocean. At this depth, few, if any, red light waves reflect back to one’s eye. Since there is no red light available, red animals here will appear gray or black, making them nearly invisible to other organisms. This helps them evade predators when there is nowhere to hide. Why are so many deep-sea animals...
Oct 15, 2004 · Estimated reading time: 10 minutes. A scuba diver in the open water is immersed in clear, pure blue light. Water strongly absorbs red, orange, and yellow light, while blue light penetrates into the depths. (Larry Madin, Woods Hole Oceanographic Institution) Light in the ocean is like light in no other place on Earth.
Shorter wavelengths penetrate further, with blue and green light reaching the deepest depths.

Jun 7, 2022 · Then, yellow, and green wavelengths are also absorbed, leaving blue and violet, which have the shortest wavelengths of visible light, and are therefore able to penetrate deeper. This, however, only happens ups to a certain depth: actually, most of the ocean is completely dark as hardly any light penetrates deeper than 656 feet, and no light at all reaches deeper than 3,280 feet.

Nov 10, 2020 · They contain molecules like chlorophyll that absorb some wavelengths of light and reflect others. Shallow areas with clear water often appear turquoise. That’s because light reaches the ocean floor. It bounces off the sandy bottom, which turns the water a brilliant blue. Extremely shallow areas still have some of the green wavelengths of light.
