What is the most visible color to the human eye?

For daytime color vision (known as photopic vision) the most visible wavelength is 555 nm, which comes out to a color part-way between green and yellow.

For night vision (known as scotopic vision) the most visible wavelength is 505 nm, which most people see as halfway between green and blue-green..

Why does the water look blue?

The reason the ocean is blue is due to the absorption and scattering of light. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water.

Why are oceans salty but not lakes?

Rain replenishes freshwater in rivers and streams, so they don’t taste salty.

The cause of the blue ring is elevated levels of copper in your water supply, which causes your water to be more acidic than is usual. … The copper stains the white porcelain used to construct your toilet bowl.

What causes blue stains in shower?

Most corrosion problems show up as blue green staining. The stain is copper deposited from the corrosion of the water piping and fixtures. … The most likely cause is low alkalinity, which typically results in low acidic (low pH) water. The second leading cause is high chloride content from salt water.

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. … The coloration both from iron and manganese and from dissolved organic carbon may occur seasonally.

You may want to point out the 4 major oceans including the Atlantic, Pacific, Indian, and Arctic. Remember that the limits of the oceans are arbitrary, as there is only one global ocean.

What ocean is the saltiest?

Red SeaThe saltiest locations in the ocean are the regions where evaporation is highest or in large bodies of water where there is no outlet into the ocean. The saltiest ocean water is in the Red Sea and in the Persian Gulf region (around 40‰) due to very high evaporation and little fresh water inflow.

Is copper in water bad for you?

Is blue water safe to drink?

Water tinged with green or blue could contain elevated levels of copper. Blue or green water is often a sign of elevated levels of copper caused by corroded pipes. Though copper isn’t bad for you in small doses, high levels of exposure can produce health problems such as anemia and liver and kidney damage.

What is the true color of water?

blueThe water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.
