Why is the sky blue science project?
The small particles of milk suspended in the water scattered the light from the flashlight, like the dust particles and molecules in the air scatter sunlight. When the light shines in the top of the glass, the water looks blue because you see blue light scattered to the side.
Why does the clear sky look blue this question is required?
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
Why is the sky blue not violet?
The smaller the wavelength of the light the more the light is scattered by the particles in the atmosphere. This is because the sun emits a higher concentration of blue light waves in comparison violet. Furthermore, as our eyes are more sensitive to blue rather than violet this means to us the sky appears blue.
Why is the sky blue essay?
Blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves (Why Is the Sky Blue?). This explains why we see the sky as blue most of the time, though you can see it is almost an optical illusion.
Is the sun black?
As with all matter, the sun emits a “black body spectrum” that is defined by its surface temperature. A black body spectrum is the continuum of radiation at many different wavelengths that is emitted by any body with a temperature above absolute zero. So one might say that the sun is blue-green!
What Colour is water?

Does water go bad?
Water doesn’t go bad. Having a freshness date on a bottle of water makes about as much sense as having an expiration date on sugar or salt. Although water, in and of itself, does not go bad, the plastic bottle it is contained in does “expire,” and will eventually start leaching chemicals into the water.
Is water really tasteless?
Our perception of flavor is based on aroma, and the five basic tastes: sweet, salty, bitter, sour and savory. Pure water does not contain compounds that elicit any of these tastes, and has a neutral scent, so we deem it “tasteless.”
What causes color in water?
Perhaps the most common cause of water color is the presence minerals. Red and brown colors are due to iron; black to manganese or organic matter; and yellow to dissolved organic matter such as tannins. Under that condition, iron and manganese dissolve in the water.
Why is tropical water so blue?
Most of the Caribbean has that turquoise blue color because of the shallow depths. The deeper the ocean, the deeper the shade of blue because the sunlight can’t reach the bottom. When the water is deeper, it absorbs all the sun rays, creating a darker shade. So the more shallow the water, the lighter the blue.
Why the sea is blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
Why is gravel pit water so blue?
It’s fairly simple: calcium carbonate, the fine limestone powder in the water, reflects the sunlight back and intensifies the naturally blue shade of water. “Very, very small white particles will also scatter blue light very efficiently.”
Is swimming in a quarry dangerous?
Quarries are extremely dangerous places to swim. Steep drop-offs, deep water, sharp rocks, flooded equipment, submerged wire, and industrial waste make swimming risky. Another risk factor is the very cold water. This groundwater inflow can keep the quarry water very cold even in late summer.
Is the Blue Lagoon toxic?
