Math Magician. 01/10/2016. The sea water appears blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than is blue (short wavelength light). So when white light from the sun enters the ocean, it is mostly the blue that gets returned. Same reason the sky is blue The ocean is blue due to absorption and scattering of light. Most of the longer wavelength of the light gets absorbed leaving behind mainly shorter wavelength for scattering. Red, yellow and green wavelength of the light gets absorbed and the remaining light we see is composed of blue and violet The bluish colour of water in the deep sea is due to (a) the presence of algae and other plants found in water (b) reflection of sky in water (c) scattering of light (d) absorption of light by the sea. Soln: The answer is (b) reflection of sky in water. Explanation: Water is colourless water attains the colour it is reflected by. Hence sea. The Answer Is in the Light. There are a few reasons why the ocean is blue. The best answer is that the ocean is blue because it is mostly water, which is blue in large quantities. When light strikes water, like sunlight, the water filters the light so that red is absorbed and some blue is reflected. Blue also travels farther through water than.
Thus, in the deep ocean, red and black animals predominate. 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 Question is : The blue colour of the water in the sea is due to , Options is : 1. Refraction of the blue light by the impurities in sea water., 2. Reflection of blue sky by the sea water., 3.Absorption of other colours except the blue colour by water molecules, 4. Scattering of blue light by water molecules, 5. NULL. Publisher: mympsc.com
The bluish color of water in the deep sea is due to the scattering of light. Option (c) Explanation: The bluish color of water in the deep sea is due to scattering of white light and we know that white light or sunlight is composed of seven colors.; When sunlight falls on the sea, the red light having the most wavelength (scatters less) are absorbed most than the blue light having less. Water acts as a selective filter. If a white light is suspended above a tank of water that was 1000' deep the colors from the white light would be filtered out selectively (one-by-one) as one descends. It is gradual. There is no abrupt interface. For example, most of the red is gone from the light after 10 feet. Some of the orange is gone White objects will appear bluish or gray underwater, and the darkness of that blue/gray appearance increases rapidly with depth. Red objects will begin to look dark brown or even black within a few meters of the surface. Down at 40 or 50 feet, even in very clear water, the world appears to be composed entirely of shades of gray, blue, and black
In this article you will get to know that why the color of sea-water appears blue. CBSE Class 10 Board Exam 2021-2022:. The blue color of sunlight has much less wavelength compared to all other colors. When sunlight falls on molecules of air present in atmosphere. They are able to scatter light of shorter wavelength of blue much more than colors of other wavelengths like red. Hence, scattered light is of blue color and hence we see color of sky as blue
The color of water varies with the ambient conditions in which that water is present. While relatively small quantities of water appear to be colorless, pure water has a slight blue color that becomes a deeper green as the thickness of the observed sample increases. The blue hue of water is an intrinsic property and is caused by selective absorption and scattering of white light Blue penetrates the deepest, which is why deep, clear ocean water and some tropical water appear to be blue most of the time. Moreover, clearer waters have fewer particles to affect the transmission of light, and scattering by the water itself controls color Expert Answer: The phenomenon in which a part of the light incident on a particle is redirected in different directions is called the scattering of light. The blue colour of the sky, the colour of water in the deep sea and the reddening of the Sun during sunrise or sunset are some examples of daily life which occur due to scattering Water. Water absorbs light, so it is usually black or dark blue. Sediment reflects light and colors the water. When suspended sand or mud is dense, the water looks brown. As the sediment disperses, the water's color changes to green and then blue. Shallow waters with sandy bottoms can lead to a similar effect Advertisement. The ocean looks blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than is blue (short wavelength light). So when white light from the.

The ocean is divided into three zones based on depth and light level. Although some sea creatures depend on light to live, others can do without it. Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet) For most of the world's oceans, your answer would be correct. Pure water is perfectly clear, of course -- but if there is a lot of water, and the water is very deep so that there are no reflections off the sea floor, the water appears as a very dark navy blue. The reason the ocean is blue is due to the absorption and scattering of light

Why Water and Ice Are Blue . In both its liquid and solid form, water (H 2 O) molecules absorb red and yellow light, so the reflected light is blue. The oxygen-hydrogen bond (O-H bond) stretches in response to incoming energy from light, absorbing energy in the red part of the spectrum
Ocean colors are color names based on ocean environments and conditions. The ocean is most typically a dark to light blue. This is due to the tendency for water molecules to more strongly absorb light at the red end of the visible spectrum such that blue light is more likely to be reflected. The actual color of the ocean depends on ocean conditions, minerals and organisms in the water Free NCERT Solutions for Class 11 Chemistry Chapter 10 S Block Elements solved by expert teachers from latest edition books and as per NCERT (CBSE) guidelines.Class 11 Chemistry S Block Elements NCERT Solutions and Extra Questions with Solutions to help you to revise complete Syllabus and Score More marks Green stays longer and blue the longest, which is why things look bluer the deeper you go.

It is one of our most visceral fears; thrashing in the deep, far below the water's surface, lungs burning for oxygen. Drowning claims hundreds of thousands of lives every year, a great many of whom are young children. Of course, exposure to water is a key factor in drownings, but there is a strong economic. The water table is an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock. Water pressure and atmospheric pressure are equal at this boundary. The soil surface above the water table is called the unsaturated zone, where both oxygen and water fill the spaces between sediments Oceans are deep as well as wide. On average an ocean is a little over two miles deep. But about 200 miles southwest of Guam in the Pacific Ocean, the water in the Mariana Trench is almost seven miles deep. That's the deepest part of the ocean Now-a-days, pH meter, an electronic device, is used to measure the pH. pH is defined as the negative logarithm of hydrogen ion concentration in moles per litre. The pH value has no unit. It can be written as: pH = -log [H+] or pH = - log [H3O+] pH Paper. pH of a solution can be determined by using pH paper
