What is the cause of blue Colour of ocean?
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 does a yellow sweater appear black when illuminated with blue light?
Yellow does not contain blue, so it will appear black under blue light. White objects reflect all light, so will appear to be the colour of the light on them. Black objects, conversely, absorb all the light, and do not reflect any, so always appear black.
Why is the ocean blue but water clear?
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.
Is the ocean blue because of the sky?
“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 sun enters the ocean, it is mostly the blue that gets returned. Same reason the sky is blue.”
Why is clear sky blue?
The Short Answer: Sunlight reaches Earth’s atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Why is the Earth’s sky blue?
Gases and particles in Earth’s atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Which planet looks blue from space?
Which is bigger Venus or Earth?
