All light penetrates water to a certain extent. However, the shorter the wavelength of the light, the more energy it carries and the less it is absorbed by the water. Blue has a short wavelength compared to red light, so it penetrates further than most of the rest of the visible spectrum.
What else can I help you with?
What are the wavelength(s) of light that penetrate deepest into the ocean?
The wavelengths of light that penetrate deepest into the ocean are blue and green light. These colors can travel the farthest through water because they are absorbed less by water molecules and particles.
What light colors penetrate the deepest?
Blue and violet: no these are reflected. Red in much better!
What are the different wavelengths of light through water?
In water, visible light wavelengths are absorbed quickly, with red light being absorbed first and blue light penetrating the deepest. Beyond visible light, infrared light can penetrate even deeper into water. Ultraviolet light is largely absorbed by water and does not penetrate deeply.
Why is there no red light below 6 meters in the ocean but there is blue light at 35 meters?
Red light is absorbed quickly in water and doesn't penetrate past a few meters, while blue light can penetrate deeper as it is scattered less and absorbed more slowly. That's why red light is not visible below 6 meters in the ocean, while blue light can still be seen at 35 meters.
What type of light penetrates the most in water?
Blue light penetrates the most in water because it has a shorter wavelength and higher energy, allowing it to penetrate deeper than other colors such as red or green, which get absorbed more quickly.
Is blood blue in the vain?
Blood is always red, actually. Veins look blue because light has to penetrate the skin to illuminate them, blue and red light (being of different wavelengths) penetrate with different degrees of success. What makes it back to your eye is the blue
How far does light penetrate underwater?
The depth light can penetrate underwater depends on water clarity and the angle of the sun. In clear ocean water, sunlight can penetrate up to 200 meters (656 feet). In murky or turbid water, light penetration may only be a few meters.
How are different wavelengths of visible light transmitted by water?
When visible light enters water, shorter wavelengths (blue and violet) are absorbed and scattered more by water molecules than longer wavelengths (red and orange). This is why water appears blue as it absorbs the shorter blue wavelengths and reflects them back. Hence, longer wavelengths penetrate deeper into water, making red light the most visible at greater depths.
Water is clear so why is the ocean blue?
Water molecules absorb and scatter sunlight. Blue light is scattered more than other colors, creating the appearance of a blue ocean. This effect is intensified by the depth of the ocean, which allows blue light to penetrate more than other colors.
Why are our veins blue in color?
Veins appear blue because of the way light interacts with our skin and the blood inside them. The blue light is able to penetrate deeper into the skin, making the veins appear blue from the outside.
Why are alpine lakes so blue?
Alpine lakes appear blue because of the way sunlight interacts with the water. The water in these lakes is very clear and free of sediment, allowing sunlight to penetrate deeply. When sunlight hits the water, it is absorbed by the water molecules and scattered in all directions. Blue light is scattered the most, giving the lake its blue color.
Some types of red algae carry on photosynthesis several meters beneath the ocean surface What color light does not penetrate to this depth?
Red light does not penetrate to depths where red algae can carry out photosynthesis. This is why red algae have evolved to absorb blue and green light for photosynthesis at these depths.
